I am sorry to hear of your pain :(
It is difficult when life just changes like this and you become inactive. And you're still young.
I sometimes think I have the body of a 60 year old woman, I'm not even thirty just yet.My physical problems are different and didn't go through an accident but I understand the dificulty.
I agree with Mealmaker, I too feel better when I move and exercise. Not moving is my enemy.
I'm sure there is someone proffessional you could turm to to get help with the heaing and pain relief, there are many natural ways of relieving pain (I too prefer the natural ways, not medications) - acupuncture used to help me (I stopped going because I had no money to pay for it at a point, but it did help me with the pains).
I wish for you to get better and all the best.
