Hi, In my opinion, this pain in your left side between the hip bone and femur is related to coxarthrosis. This is a very common disease of the hip joint in women and consists of the rheumatic destruction of the joint. The risk of this disease increases with age, obesity, overusing the joint. I suggest you consult a rheumatologist, for a physical examination, and X-ray examination to put the diagnosis. Meanwhile, you should: -take an anti-inflammatory drug, Naproxen once daily, for pain relief. -exercise more -try to lose weight, and eat a healthy diet -and take hyaluronic acid supplements. If lifestyle changes and treatment don t improve pain, you might also make corticosteroid injections. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr. Suela Gjata, General & Family Physician
