i woke up in the middle of the night with a pain in my right leg below my ankle when i looked at my leg i saw a bruise and it hurt when i touched it but i know i didnt bruise my leg. so i thought it might be a bloodclot and i took a pantyhose and tied it really tight a few inches above the bruise then i went back to bed and i felt my vein beating hard so a few minutes later i untied the stocking a the mark and the pain were GONE . I think it might have been a blood clot cuz i had an operation 7 mos. ago plus my grammy has blood clots in her leg . so any help or info would be appreciated. thnx
