Last week I had a tingling sensation in my right foot. It lasted for about 2 days and went away but I am now obsessing over it. I think I may have a blood clot and am constantly checking the color in my feet, checking for any swelling, and checking the pulse in my foot. I don't go back to the doctor for another 3 weeks and I am scared that I will not make it. PLEASE HELP ME! Should I be worried or is my constant worrying and checking my symptoms just making me worse? THANK YOU ALL!
