Fascia encompasses the whole body and so helps with MANY kinds of diagnosis or dysfunction.
Here are some common issues people seek out MFR for:
Traumatic Brain Injuries (TBI's)
Pelvic Floor Dysfunction
Chronic Fatigue Syndrome
Jaw Pain (TMJ)
Myofascial Pain Syndrome
Women's Health Issues
And... "getting old". That feeling of "getting old" tends to be nothing more than a build up of untreated fascial restrictions.
