One question I have is whether or not my running caused my blood clots. I don't remember if I've already posted the answer to that question, so I'm doing it again to be sure the answer does get posted.
When I left the ER at the hospital and went to my new room, I asked the doctor if my running had caused the clots. He said, "No". He said that running should help avoid clots rather than cause clots. Running improves blood circulation while blood clots are formed when blood coagulates from being stagnant.
