I broke my femur back in August of 2004. I was wheel chair bound for the first two months, but I think that was mostly because of the other injuries I also had. I actually had an 4-wheeling accident on my 16th birthday (I think the fact that I was so young helped a lot with my healing process), I broke my femur, collar bone, elbow, and pulled my ACL - all on my left side. My arm was in a cast for a while and then in a sling for my collar bone to heal which meant no crutches. Once out of the wheel chair I began physical therapy and it was rough, but I didn't take any thing for pain other than the week I was in the hospital right after it happened and maybe the first week I was home (I really do think I have a high tolerance for pain).
I spent about a month on crutches and a few more months in the leg brace (that I absolutely hated! but took it upon myself to not wear as often as Dr's orders). Less than a year later (June 2005) I had the rod removed from my femur - I was told to expect to be on crutches for 3-5 weeks and I ended up walking that same day only to use crutches for a little bit the 2nd or 3rd day because of walking too much (oops).
Five and a half years later I can still feel the affect from the accident. I don't limp at all, but I do baby my left leg a little bit. I can't kneel down or bend my left knee as far as I used to, and sometimes it bothers me more than others - I'm not sure if this is because of the whole ACL thing or just everything all put together.
This stuff doesn't really effect my life though. I just keep pushing through it and try to ignore it.
The thing that upsets me most about the accident is that I used to be into gymnastics and even though it was probably the thing that saved me from having much worse injuries or even dying, I can't really do it anymore (I was/am flexible and have muscular legs). I can - but I have to be extremely careful and I don't think the doctors would recommend doing the stuff.
Overall - I think the thing that helped me heal the fastest was the overall faith I had that I'd get better and I wouldn't let this one incident hold me back. My biggest recommendation to the healing process is to stay positive and never give up on anything.
Also, remember not to be afraid of anything. It's okay to do some of the PT stretches on your own (but with caution and don't over do it!). And don't be scared to go back and do what ever it was that put you in this situation in the first place (no one really thought I'd be able to get back on a 4-wheeler, but I was riding one while still in the leg brace).
Oh - and I think the only medications I took was baby asprine as a blood thinner as to avoid any possible clotting.
Hope everyone who posted on here gets better (and fyi - the pain I get in my knee is likely the ACL issues and it's not unbareable pain).
