stick with it, as someone who has really been on and off physio since 2006,I know it does help !
If you take any injury , you naturally want to rest it , not force it to do anything , yet most physio involves working / stretching the affected limb.Yes its painful but without it you may not heal properly, and possibly not get the full use of the limb afterwards..
Frustrating , but time does pass.Keep a positive mental attitude and do all the things the physio requests.I was in plaster for 12 weeks with a broken arm and leg, with which it is fecking awkward to do anything , but with resolve and determination I could do some tasks, look after myself to some degree, gave me self esteem and resolve, and I do believe it speeded up my recovery...
Best wishes for your speedy recovery.
