About 3 years ago I had severe chest pains and thought I was having a heart attack so I went to the ER and they couldn't find anything wrong. I had these chest pains over time but my doctor checked my heart out with every test and they were all normal. Last year when I took bactrim the bottom part of my tongue got a white film and it hurt very bad, I also had the severe chest pains again but I still did not connect it with bactrim. I started taking bactrim on July 7th-Monday and by Thursday I had the white painful film under my tongue again, and I actually started to connect it with bactrim use so I quit taking it but by Saturday night I began itching and getting hives. Sunday night I started having the severe chest pains again and went to the doctor on Monday, he has scheduled a cat scan for me, I have already had the endoscopy and chest x-rays but nothing. I sat down and began thinking and every time I take bactrim I have the severe chest pains. It is Saturday July 19 and I still have the chest pains and itching.
