hello and let me tell you as myself a longterm chronic pain sufferer i can understand how you feel and i was depressed for a while.
these my friend are the things they don,t tell you and i have argued with my pain management on many an occassion" why only treat the physical side and ignore the mental affect it has on you"
then i realised that only i could overcome the longterm effects because if you let it get you down it does.
there is always a way to overcome the not leading a normal life senario and i found mine using this e.health forum and advising and supporting people.
its hard and i totally understand as my complaint is spinal so my walking is affected.
im not sure if the physio is causing the temp but it could also be any medication your on.
keep in touch we are always here to support you anyway we can.
