Welcome at HCM.
I have read your question completely.
If you are getting pain at mid thigh or lower part of your thigh then you should get it evaluated without hesitation.The best will be to have a x ray
of part.This can be due to protruding screw or incomplete union at fracture
site.This can also be sign of an early infection.
Removal of it is not necessary if every thing is fine or there is no infection or protruding screw .
Take a good analgesic
.This will help in reliving your problem.
With best wishes.
