Thanks for posting your querry.
First, i would like you to get Xrays of your thighs done again as severe pain
after bone injury
13 years back is unusual. I would also like to know what treatment you underwent for the same. These will help diagnose the problem ie: the sourse of your pain.
Till you can visit an orthopedic surgeon and also get the xrays done, you can take pain killers and apply locam analgesic
ointment/sprays for symptomatic treatment.
Hope you feel better soon.
