I'm not sure anyone can answer your question except a real doctor. I suggest going to see one. There's a place here in Washington called CBR Medical (Google it), you can go talk to the doctors there, if they approve you it'll cost $200 - If not, it doesn't cost anything. You will either walk out with the same $200 you walked in with, or you will walk out with your authorization. They have clinics every weekend.

Good Luck
