When I lay on my back my chest hurts,if I put my hands on my chest,like the middle of my chest,it is worse and I feel like I can't breath. I will also have chest pain sometimes with just having my bra on. The past few months I have also been having some severe dizziness,especially if I squat down and stand back up I get so dizzy I get nauseous. I have been so tired all the time lately all I want to do is sleep,but can't sleep. I have told my primary care physician all of this and he just said he's never heard of anything like it,but it's probably all of the medications I take. I'm disabled because of my back and take pain medications and muscle relaxers and arthritis medication. Should I continue to persue this with another Dr? It seems to be getting worse and I'm getting concerned about it.
