Thanks for your query.
Your history suggest that probably there is dislocation of your hip joint and which you feel is most probably the head or greater trochanter of femur
. posterior dislocation of hip
is more common that anterior dislocation. It is also of utmost important to exclude the fractures
of the neck of femur or rim of acetabulam. Therefore i ask you to go for a x-ray of hip joint both ap and lateral view to exclude fractura. If there is only dislocation without fracture some maneuvre may be done to correct it without operation. Otherwise operation should have been done. Consult a orthopedic surgeon, get locally examined and take his opinion.
