What kind of doctor can i go to if i can't get a diagnosis of my debilitating symptoms? my quality of life has went downhill fast.

Primary care doctor: Each person should have a primary care doctor, who can treat the problems and refer to specialists. Primary care means pediatrics, family medicine, general practice, or internal medicine. Find a doctor who can spend time looking at lots of symptoms and issues... Which means one must buy really good insurance that pays for multiple visits and long visits (unlike hmo's, medicare, and medicaid).
