Its a phyisotherapy technique that deals with the restrictions in the connective tissues. These restriction can be caused by inflamation, trauma, surgery and as my therapist tells me negative emotions long held onto. regular physio just didnt work for me so i tried this and it worked ! i no longer have pain !! pain that my gp dianosed as fibromyalgia! the therapist uses a range of techniques to release the fascia which is where the knots or restrictions lie. it cleared up my achilles tendonitus, and helped on my shoulders and knees.But that said, i am lucky that I have a therapist 10 miles away who regularly vists the states for up to date training. Ps she has also sorted out my friends slipped disc which regular physio was making worse. x
