Okay so when I drink a lot of caffeine or am so unfortunate to be around someone who is smoking a cigarette I feel my left arm go numb, my heart rate will increase rapidly and I feel like I cant breathe, this will last the rest of the day or until I run or do something active...any thoughts on this??? The akward thing is it happens with both caffeine and cigarettes...also when I smoke a cigar every now and then (dont too often anymore but back in the day) and drink a lot of caffeine I would also notice little bumps underneath my tongue...someone please help!
