My left calf down the left side of it hurts. Its been hurting since yesterday. I have a strange phobia about blood clots. Ive had it checked before, like a million times. Ive even had a ultra sound on my leg before. It also looks a little pinkish to me. My friend said it kinda looked id leaned up on something and it left a mark. She said it wasnt really red, just a tint of it. Should I be worried?? I hate having this fear of blood clots
