Hello, I have had that feeling but it started with my fall that resulted in a THR.! I was diagnosed with pudendal neuralgia. It is a rare complication with THR. Google it for more information. I pray that is not what it is because it is terrible to endure. I had 4 stem cell procedures and pelvic therapy and it eventually went away. Also, I hate to hear you have bursitis as well! I did also and my turned out to be a torn gluteus minimus tendon which can also be a complication of the surgery or just caused by overuse (maybe injured in PT??) Or deterioration of tendon. Only a MARS MRI can diagnose this. It took a long time to get my Dr to do the MRI. I suggest you ask for one ASAP. They will want to do steroid injections for bursitis but that just weakens tendons more. However, I think insurance requires this conservative measure. God Bless you! I know you are enduring pain.
