The best advice we can give to you is to listen to your body. If your doctor tells you that you're fine, but you don't feel fine, make another appointment. As you are listening to your body, educate yourself on what's happening. Use the library and the Internet to find out about your symptoms and what tests are usually run for them. Have your doctor write everything down for you. If your doctor denies you a particular test or a referral to a specialist, have the doctor explain in writing the reason for the denial. If the doctor won't write it down, you should seek counsel by a qualified attorney.
