Hi, I am a 22 year old male and have been experiencing bad chest tightness and dyspnea for a while now. It began very minor and then grew worse and worse over the past few years. I have been to many doctors but I feel as though someone is missing something. I also went to a psychologist and nothing was found that would cause these symptoms. I have seen pulmanology, cardiology, GI, ENT, Neuro, Internal. And still no diagnosis. I have been put on many medications but nothing is helping. Only thing found was high liver enzymes but I was told it was because I was heavy 250 ( I lost 30 lbs thought im now 220) My father was diagnoses with myasthenia Gravis but I do not have it from what the blood test and EMG showed. Also these symptoms seems to get worse when I had to start taking Vicodin more often (1 pill a day) instead of 1 every couple of days for my migraines. Is there any disease that Vicodin would make worse? Or could the drug it self cause these symptoms? Thank you for your help.
