Because chronic fatigue syndrome and myalgic encephalomyelitis(ME/CFS) are not well understood, different people get different results from the same treatment. The most important approach is talking to your doctor about all of your symptoms and finding a customized treatment regimen that works for you.
In searching for information for you this Dr. from the Twin Cities area came up as a Dr. you may want to look into. names to look into.
Michael Dole, M.D.
3408 Dakota Ave. S., St. Louis Park MN, (952) 924-1053
I found one in Sioux Falls:
John Hansen, MD - Sanford Health
Sanford Pain Center
1210 West 18th Street
Sioux Falls, SD 57104
Please remember that I do not know these physicians and HealingWell does not recommend them as both physicians were found on the internet. The best thing to do is to talk with other people who have been treated by any Dr. for CFS, do your homework well and choose a physician. If you are not happy with your choice be your own best advocate and look for a Dr. that meets your needs.
One more thought, join social site; this is the link to The CFIDS Association of America
Again, HealingWell does not have any personal connection with these Drs. They were found by my personal search per your request. I am not recommending either Dr., just providing you with a couple of names for you to research.
