I am a 51yr old male. About a month ago I began having headaches daily. I have also felt weak and fatigued on a daily basis, every few days it gets to the point that I can barely stand up and have almost fallen several times. I have had blurred vision at times, dizziness, numbness and tingling in my legs feet and arms (i couldn't cut my own food), swelling/pitting in my feet that is worse on the R side, freq. diarrhea, abdominal pain (occ), ringing in my ears (occ.), rapid heartbeat at times
