That's my first reply. If you don't have health insurance my first questions would be, are you stressed out ie. look seriously at your home/work conditions. If this is the problem then de-stress. If this is not the reason then I would seriously say to go find a low cost clinic or sliding scale. There could be many health reasons for this. I have MVP with dysautonomia (genetic) which exhibits the same kind of symptoms. I would listen to yourself and press forward. If you have a doctor that doesn't listen then make him/her listen. Do not just "let it go".
