I was kicked by a horse in the middle of my thigh over 2 years ago. It obviously really hurt and I used a crutch to walk with for a couple of days but never thought to go to a doctor. It seemed to heal but 3 months later started to ache. It still aches, generally if I have walked or exercised a bit the previous day. It comes and goes in waves. Could I have broken it and if so, is there anything that can be done now?
If you had broken the femur, you would have known it, as you would not have been able to stand on it. I guess, it would have been possible to have a very tiny crack, which did not disrupt the periosteum, but that would have healed a long time ago.
However, it is possible to damage the large muscles that do around the femur in the thigh. It is not uncommon to develop myositis ossificans within the thigh muscles, especially within the quads.
In this, a large hematoma, or bruise, develops in the muscle. Then as it heals, scar tissue starts to form. In some cases, bone can actually form within this area also, this is the myositis ossificans.
This is seen in football players, jockeys, calvary officers (where their swords would hit on the outside of the thigh), bull riders, just about anyone who can get deep muscle bruises.
But, it is very common to have scar tissue form in the muscle after a significant trauma, even if the bone does not form. Scar tissues does not stretch as well as normal tissue.
If it is really bothering you, you might want to see an orthopedic surgeon. An x-ray of the area will tell if you have this problem. Good luck.
