i have had ever increasing health issues. been to the doctor but will call again tomorrow. i am on methadone for severe periphrial neuraligia in my right foot from two back surgeries. the methadone is the only thing that helps, I tried everything else for 8 years. It gives me real bad constipation which I thought was the reason to the new issues. Stomache aches, which are now more than that, sort of sharp pains in the low stomach, Doc said dont worry, that I am stressed out only. But now, the symptoms are chills even when sweating, nuasea and vomit about twice a week..lost weight while not even trying even though I cant eat a full meal, I get full fast. I am 6'2" 200lbs...was 215 a month aga. I believe what I have is serious and I have to get my doctor to listen. You have any advise?
