Had a femoral nail removed after a year, nothing like yours though as I could walk on mine immediately although I had to use crutches. I was only allowed to have half weight bearing on the leg for a few weeks before building back to full weight bearing over another month and i think it was a while longer before I was allowed to run on it.
Glad to have it removed as it was causing or exacerbating bursitis in my hip and running on a rigid steel pin was very uncomfortable as it lacked the shock absorbing flexibility of bone (felt like my femur and hip was being hit with a hammer).
In my case it was well worth doing, a few weeks of hassle/discomfort for complete normality to be restored.
Infection isn’t the only reason to remove them – if it is having an effect on your quality of life it can be worth having them removed too, especially if you are still reasonably “young”. As with all operations, there’s a balance of risk with general anaesthetic, post op infection etc. to consider.
