For the past several days my feet have been swelling on and off, not normal for me, this morning just a portion of my right foot fell asleep, and it did not wake up for 20 to 25 min, it was completly numb i could not feel my toes. then on and off all day i have been getting leg pains and cramps. my feet will get tingaly but not fall asleep. now I am having pains in my heart area. they were really severe and distinct. not gas pains. the heart pains have subsided some but are still there. now my left arm/sholder/neck have pains not sharp pain just constant pain. my bp is normal. do you know what is going on.
