## Summary

A VTuber recounts how a seven-hour RimWorld livestream without a break led to deep vein thrombosis (DVT) in his leg, a condition that can be fatal if a clot breaks free. He shares his symptoms, emergency room experience, diagnosis, and treatment, plus a reminder for anyone who sits for long periods: move regularly.

### Key Points

- **Personal story and disclaimer** [00:03] — The video opens with a disclaimer that the creator is not a medical doctor and that viewers should consult professionals. He is sharing his own experience.
- **The 7-hour stream** [00:20] — During a Friday mystery box stream, the creator chose RimWorld and played for 7 hours without moving from his seat, causing blood to pool in his legs.
- **Blood clot forms** [01:21] — A clot formed in a deep vein of his right leg, starting about 2 cm below the knee and extending 10 cm down. The condition is called deep vein thrombosis (DVT).
- **Risk of the clot** [01:49] — The danger is that part of the clot could break off and get stuck in something vital like a lung. This is a deep vein thrombosis, abbreviated DVT.
- **Waking up with symptoms** [02:44] — He woke up with a cramp in his lower calf, initially ignored it, thinking it was dehydration or low potassium. The pain was mild at certain angles.
- **Decision to go to the ER** [03:11] — When the pain became intense enough to make walking difficult, he chose to go to the emergency room, reasoning that embarrassment is better than dying.
- **ER visit and triage** [03:38] — The waiting room was empty, so no queuing theory was needed. A nurse checked his vitals, and he noted an overlap between computer science and healthcare triage.
- **D-dimer test** [06:52] — Blood was analyzed for a protein fragment called D-dimer. An abnormally high amount strongly suggested a blood clot. Ultrasound was unavailable that day.
- **Klexane and home care** [07:21] — He received an injection of the anticoagulant Klexane and was told not to take aspirin, avoid injury, and go straight back to hospital if he had difficulty breathing.
- **How anticoagulants work** [08:12] — Anticoagulants stop clots from forming and growing but do not dissolve them. Enzymes break down existing clots, so blood flow (movement) is necessary. Compression stockings help.
- **Prevention for streams** [09:54] — He now has chat remind him to get up and stretch every half hour during live streams.

## Transcript

math and other subjects that catch my interest. I also live stream playing video games. I'm going to talk about how due to a mistake I made in one of these live streams, I could have died. Also, this video talks about some human body
health things. So, if that squeaks you, please watch another one of my videos. I'm not a medical doctor. All my qualifications are in mathematics and computer science. So take none of this as medical advice. Talk to your health
care professional. Every Friday I have a mystery box stream where I do a stream mystery box stream where I do a stream of an unannounced game. This time I chose to play Rim World, a science fiction colony simulator game with chat
alongside me and an engaging game before me. I played every hour that passed. So I thought to myself, just a little bit more. I want to complete this thing or do this other thing. And as I played, something else was happening inside my
body. I had been sitting in the same st seat for quite a long time. Normally, as you move around, your leg muscles help to squeeze and pump the blood back into your body. However, since I've been sitting so long, the blood was pulling
in one place. And when blood doesn't flow, it can clot. During the 7-hour V tubing session, a clot formed in one of the deep veins of my right leg, starting
the deep veins of my right leg, starting about 2 cm down from the cleft of my knee and extending all the way down to 10 cm. The risk with this type of clot, also called a thrombosis, is that part of it could break off and get stuck in
something vital like a lung. Because this condition is a thrombosis of the deep vein. It is also called deep vein thrombosis or DVT. My session of Rim
World ended when one of my poems in the game caught a light and ignoring the primary school advice of stop, drop, and roll. Ran into the colony store room
spreading the fire. Soon, everyone in the game died either directly from the fire or collapsed after breathing in the superheated air. I went to bed that day. I went to bed that day feeling accomplished. A long stream with what
was for me a large number of viewers. All adding to those precious public watch hours that I need to monetize and recover the money I had invested in my model and streaming setup. I woke up on
Saturday morning with a cramp in my lower calf, which I mostly ignored. The pain wasn't that bad and it only happened when I put my leg at certain
angles. It could be anything. Dehydration or low potassium, both problems that are quite common in the near tropical climate in which I live. But there was a concern in the back of my head. What if this was another DVT?
because this wasn't my first EVT and the pain felt very similar. However, on Saturday, the pain at sometimes had become so intense that it was difficult become so intense that it was difficult to walk and I decided that even if this
wasn't a DVT, it was better to have the embarrassment of going to the hospital for no good reason than dying. So, I had a friend drive me over and drop me off at the emergency room of the local hospital.
Surprisingly, the ER waiting room was empty. Not a single person there was waiting for anything. I walked up to the triage nurse's desk and quickly triage nurse's desk and quickly described my symptoms. It is a triage
nurse's job to work out from the symptoms how urgent my condition is and then prioritize my case with the other patients. There is an interesting overlap between computer science, healthcare and mathematics called
queuing theory. How best to order incoming jobs so the urgent tasks get dealt with but without getting into a situation where less urgent cases are
never dealt with because of a continual flow of more urgent cases. However, since the waiting room was empty, all of that was irrelevant. As soon as I turned
my head, there was a nurse there asking to check my vitals. After embarrassing myself by forgetting what year it was in the awareness test, I was moved to the
examination room. There, I talked to a very nice doctor wearing a Progress Pride lanyard. Thankfully, nothing in this event related to my gender or my sexuality. But it is things like this which make me more feel more comfortable
that if I needed to discuss stuff that related to those topics, I could. Thankfully, this isn't one of those situations. He asked about my symptoms. I did the same thing to do whenever I'm communicating stuff to someone who's
trying to debug a problem. Start with the most serious symptoms. give context about why I consider these symptoms serious. Then go on to the next most serious symptoms, repeating that until I've gone through all of the symptoms,
and of course, I answer any of the questions the doctor gives me. I've noticed that a lot of people use a more narrative approach, starting at some beginning point and then just talking about one event after each other, which
seems weird to me personally. Anyway, the doctor thought it was very likely that I had a clot, so they gave me a blood test. I'm always a little bit nervous with blood tests. to keep my mind off it. Normally, I give the person
who is taking the blood test a lecture on homotopi type theory. So, there is a doctor out there who got a sneak preview of my next video in the spilling the hot tea v video series. After the blood was drawn, everything became started to
drawn, everything became started to become overexposed as my eyes dilated and I feel felt woozy and almost passed out. I've got out. I've got a vaso vagular reflex sync sync cope
a vaso vagular reflex sync sync cope thing where I often pass out when blood is taken. While that was happening, my blood was being analyzed. Searching for blood was being analyzed. Searching for a little protein fragment called
Dimma. And by detecting an abnormally high amount, that means it's very likely that I have a clock. Normally the next step would to give me an ultrasound to
confirm the existence of that clot. However, all the ultrasound techs had gone home that day. So they gave me an injection of an anti-coagulant blood thinner called Klexane and then sent me home with some instructions. Don't take
aspirin because it can interact badly with the cleane. Don't get injured. If I have any difficulty breathing, go straight back to hospital. And honestly, straight back to hospital. And honestly, if I suddenly can't breathe properly,
I'm going to the hospital anyway. Even if the doctor had not given me that advice, there are two important things I've discovered about Klexaneate injections. After you in get injected, you will feel a rather strong compulsion
to touch your skin near the injection site. Do not do this because everything will bruise. Second thing I've discovered when I have to self- inject
Klexane is to put some power metal on before you inject yourself. The added stimulation from the music helps keep your mind off the of stabbing yourself
with actual metal. Now, anti-coagulants like clane don't dissolve existing clots in the body. There are two separate but equally important systems. The platelets that create clots and the enzymes that remove
them. The anti-coagulants stop clots from forming anti-coagulants stop clots from forming and growing. It is up to the enzymes to break the clots down and for that to happen blood flow needs to occur. So I
have to wear compression stocking on my legs and make sure to keep my legs moving. Unfortunately, the next time they could do ultrasound on my legs was
Wednesday. So I had two days where I had to wait nervously. And in those two days, something had dramatically changed. Off the coast, a cyclone was
forming, threatening to bring dangerous winds and flooding rain. However, at the moment, it was just hovering off the coast, looming there. I was now very concerned if I did not get my clot attended to before the hurricane struck,
I'll be stuck behind flood waters. Thankfully, I was able to get there before the hurricane moved onto land. And with the sonogram confirmed, I was And with the sonogram confirmed, I was prescribed a month's worth of blood
prescribed a month's worth of blood thinners and a follow-up genetic test. Because while super clotting is a beneficial gene in Rim World, it isn't beneficial gene in Rim World, it isn't in real life. In my live streams now, I
have chat remind me to get up and stretch and move around every half hour, which is what I believe is called a stretch goal. If you wish to help reminding me, you could subscribe and watch my live streams or any of the
other videos on various topics such as mathematics, be tubing or anime anime.
