Having psoriasis for few years now, under going medication currently band also have issues of gastritis. Used to smoke and drink but now not regular. Recently experienced an uncomfortable feeling on the left side of the chest post every smoke, felt a bit of anxiety and a throbbing sensation. It stayed for an hour and then was normal. Totally quit for few days now but still at times feel the tingling sensation when I get the craving for smoke and subsides after some time.
