My 18 year old son has May Thurner. You don't always have a weird looking leg! Although my son does because he has 2 rare vascular diseases affecting the same leg. I was really worried about the vaccine giving him extra clotting issues since those with that diagnosis are susceptible to getting very large/long clots in the leg. He will probably have to deal with a clot sometime in the future even though he did not get a Covid vax. Not doubting the possibility an inaccurate diagnosis though. My other son had cancer last year at age 19- also not vaxxed! So, the vax isn't always to blame. I would have 100% blamed his cancer diagnosis on it if he was vaccinated though. And yes, I still hate the vax and do believe it is sadly injuring people and causing deaths. But, it wasn't the cause in the case of my children.
