I take tegretol for mybipolar and bistollic for blood pressure. I live in Helena montana but do not work in the extreme cold but I am a very active 26 y/o male. For about 5 wks I have been having swelling in my toes and tingling and subcutaneous itching in the last digit. My circulation seems to be involved because the last digit will sometimes turn red and almost blue with the swelling which can make my middle toe almost twice it's normal size. I was told the very bad reaction I had to tolecten medication was allergic and at one point it had made my fingers and toes have red and white spots. Could this be a dangerous reaction to my medications?
