My son has acne (as most trenagers do) he was given a business card for a local research study on new acne medicine. I signed him up. I did not know that the FDA.GOV actually has patient links to clinical trials. I saw the results of a fibromyalgia study that says a group of 40 had reduced their pain by belly dancing. So if you want to voluteer for some research studies in your area or just look at the studies that have been completed. Go to clinicaltrials.gov
They usually give you the treatments for free and pay for your time for follow ups.
