Don't give up. Keep going back to the doctors and tell them you need help, options, results, solutions, etc. If a particular doctor is out of ideas or options, fire them. Get a new doctor and try again. I lived with a bad stomach infection for years because of incompetent doctors. I'd express your concerns with your primary doctor and say you need options. If they are stumped or send you home with a redundant treatment option, call your insurance company or visit their website and get a list of primary care doctors they cover. Pick a new doctor. My advice would be to pick a young doctor.
