I personally know of two people who have been prescribed wellbutrin and had terrible sides. I am talking about gradually going from anxiety and depression to full blown schizophrenia where one person believed that everyone from family to the hells angels were out to get him killed. It was terrible. I also know of a second person who was prescribed it and it made them feel terrible, lagged, and worse off than before the meds. Never heard of chest pains, although I would not doubt it.
Is it possible that you speak to your Dr about switching to something else? Or possibly going through Rxhealth and getting some thing different?
With all this being said I think that you should mention this to your physician. Funny chest pains that are recently knew and not looked into could pose as more serious problems and should be looked into.
