Lately I have started to do things to keep healthy. I began exercising, cleaning up my diet, taking vitamins (multi, b1, calcium, fish oil, antioxidant, biotin, folic acid) and a low dose aspirin each day. Lately though, my legs and feet have began to have little white blotches all over them and my feet feel kinda cold sometimes. Also my legs will feel like the vein in twitching or there is something moving through them, kind of a tickly wierd feeling. The movement also happens occasionally in my neck, face, lips, and under my right ribcage. i always have hard time taking in breath and i always have to cough by force. i just had blood work and labs done and they were all normal. what could be causing this, and are these symptoms related?
