Hello friends! I have PMR and GCA. For the past several weeks, I have been having severe pain in the coccyx and lower back. I have had X-rays which showed some osteoarthritis in the sacroiliac joints and symphysis pubis, but nothing notable in the coccyx area. This pain awakens me during the night, and stays with me most of the day. Have any of you experienced anything like this with your PMR? I am currently on Prednisone 4.5 mg, and Actemra monthly infusions for the GCA. The nights are miserable. I have also tried icing, heat, epsom salt baths and swimming. I am even taking some pain med. at night. The physical therapist gave me som exercises, but I hurt more after doing these exercises. Any suggestions or thoughts if this could be PMR related would be helpful.
