<<Disclaimer: Verify this information before applying it to your situation.>> In my Case the HMO (Central Massachusetts) was very responsive. Even though I had symptoms dating to childhood, they did not get severe until a period of severe stress (defending my doctoral dissertation). My HMO doctors diagnosed me in less than TWO months. This was accomplished at practically no additional cost (outside of premiums). Not a holiday goes by that my family does not thank the doctors for their quick diagnosis. Whoever your provider is you must continue to seek answer for your ailments. Persistence is the Key. Forgive the Typos, I have not yet mastered this new communication software (keyboard mapping).
