I keep worrying that I have a blood clot in my leg. I have been to the ER twice with it and they did two ultrasounds, blood work, and a CT. All those tests came back normal, but my leg is still bothering me some. They said I pulled my calf muscle. What is worrying me now is that my big toe went numb on the same leg (however I have been on my feet since 6 this morning and just now sat down.) I read horror stories online where people say the doctors missed the clot. I don't have the risks factors except I travel some but not long flights or car rides. I'm in shape too. Should I just let it go and believe it's a pulled muscle?
