Thank you bigfut , that's very helpful . I have been weighing the pros and cons and slowly coming to the conclusion that it may be a waste of time , especially as I have a lot of joint problems and spinal damage that causes pain anyway. I will think it over some more but I guess even if it did help , it may come back once they wear off. I have an alternate for now in so much as physiotherapy was offered , once it becomes less painful to move.
Thank you for your reply hun :-)
