What Does Pain On The Left Side Of The Hips Indicate?

After being on a ladder for several hours I developed a sharp stabbing pain in my left upon stepping off the ladder. I took Alieve for about two weeks with minimal benefits. I’m 64 years old, in good physical condition. The pain keeps me from running and working out as the pain continues with each step. I did see a oropediadic Dr. And he felt it could be referred pain from my back. He took X-rays of my hips and all looked good. I’m just coming off a period of prednisone with little change One additional symptom is that on occasion I get a vibrating feeling in the pain area similar to a phone vibration for maybe a second. I’ll return to the Dr. But I thought I would see what your thought are concerning this pain
