I was diagnosed with hip dysplasia several months ago. I started treatment with a cortisone shot to the hip…several weeks later I started to experience pain in the buttocks area, eventually the pain moved and centered on the coccyx area. I then had a cortisone shot in the coccyx joint . This cleared up the coccyx pain immediately (hip pain was gone, also). 3 months after the first hip injection I needed another injection in the hip for the pain…the pain is repeating..lots of pain in the buttocks/coccyx area. My question…is the hip injection causing the referred pain in the buttocks/coccyx area OR are the two areas linked by tendons and ligaments. Seems like the cortisone shot in the hip area is too aggressive for pain management…also, I have been doing PT treatments (5 months) along with the shots to address the hip displaysia
