Question: Hey doc. So i started smoking cigarettes and marijuana at the age of 15. Developed allergic reaction at 17 and also found out i had an ulcer. Everytime attempted since then my heart beats rapidly as if i was having a panic attack, so after a while i stopped the marijuana. I tried herbal tea and weed cake and the same thing happened.Even to this day it's the same thing and i'm 26. Also ever since then i have not been able to burp or belch. If i attempt to do any of the two it just rushes up to my chest and stops as if its being blocked.About two years ago i got food poisoning at a hotel and i felt the need to vomit but couldnt. My chest was in so much pain, eventually it forced its way up and when it did the vomit and very loud belches came out simultaneously.So ye in the past 9 years i've only belched and vomit once.Now recently i've been having this sticking pain in my chest,it comes and it goes sometimes find it hard to sleep. Not sure if both symptoms are linked but i did some online research on the sticking pain and thought it was pericarditis. Any ideas?
