About two weeks ago i was smoking and everything was fine but then the next day i couldnt breathe. I didnt know what to do because i didnt want to go to the doctor. After about 3 days of not breatheing good i finally went. He said that i was doing something and i must have pulled a muscle that i needed to breathe and he prescribed 500mg of Naproxen. Now its been a while and i want to smoke again but im afraid. I am still on the pills. 500mg two times a day. Will anything bad happen if i smoke while on these pills. Also what are the chances of this happening again. One more question. When the doctor asked, any recreational drug use and i said no, will that effect his diagnosis? Maybe it wasnt a pulled muscle but a reaction to the marijuana. If so why dit it happen this time, my 14th time smoking?
