I have chronic back pain and take 400 mg gabapentin 2 times day. I also take welbutrin and lexapro for anxiety and depression. I take metoporol and isosorbide for chest pain associated with myocardial bridge. Wed. I started getting discomfort in my chest and it got worse, so i started to drive myself to the hospital because it was radiating to my jaw , i got about 5 min. out and the pain was getting intense. i felt lightheaded, short of breath and like i had something in my chest expanding. i felt like i was having a hot flash at the same time i could feel it in my neck and ears. I am 56. I felt like i wanted to just lay down it hurt so bad. at hospital about 1/2 hr there they gave me 3 baby aspirin. id say about 10 minutes and i was starting to feel better and pain was going away. when the pain finally went away, i was very exhausted and got a little throbbing headache. Felt ok laying around and slept a lot at the hospital overnite, day after i went home. my legs feel like there heavy. i get short of breath, lightheaded. and headache all day. all my test including stress and echo was normal. i'm confused they said my heart is fine.
