Phil i hope your on about the clutch mod and not tabethas problems, Tabetha it sounds like your going through hell mate, i know what you mean like im 41 and have joints that do what and go where they want through 35 years of running.. feel like 90 when i get up on a morning cant walk proper sometimes....
I can only straighten my right arm to 135 degrees, instead of straight due to elbow smashed, have genu recurvatum in both knees, with hyper mobility and hyper extension along with laxity of the cruciate ligaments in both knees, so they back as normal but also forwards and sideways too!!
