Oh wow - this is scarily familiar! I also had past leukemia fears and noticed blood spots after vax (some went away so was obviously from hitting my leg and not realising, others still here). My leg pain is still around and it's driving me crazy - I'm constantly worrying I have a DVT that will become a PE at any time, so if I feel short of breath for a second I get sent into major panic. I'm so worried the ultrasound missed something but I'm sure it's unlikely...Doesn't help that the calf with the pain has more visible veins & is slightly bigger (normal asymmetry I hope). I think DVT pain is also more throbbing and intense, mine is just like a sharp twinge for a few seconds which then releases (sometimes with some muscle twitches in the leg...not sure if that's a DVT symptom) it's all a bit weird!
