Hi. I have been dealing with this for almost a year. Anyhow for the first 4 months I was in bed full days from the pain. When I started to push myself I could barely walk through a small store. Now I have worked up to being able to walk 20 minutes but walk through big stores like Target. I often feel like my legs will give out and limp.My docs said it just feels that way but won't. Since they have been wrong about most things with me I am not pushing it to see. I was extremly active before this happened. I have a very hard time now knowing the balance of pushing but not doing too much. I fear damage still but I do see how important it is to not let your muscles waster away. My pt experiences have been really bad and the guidence by my docs are very vague. I think for me loosing my ability to be active and do has been mentally hard. Right now I guess I could care less about being a sporty person I just want to be able to do daily stuff not in pain. I hate having to push to do small things. Oh by the way I am young not to say it is different but at 29 I should be more active. Good luck in finding te right balance for you.
