I have these hard, painfull “balls” along my spine and SI joints. They feel hard as bone and they wiggle around when I press on them. They are incredibly painfull. My rheumatologist said to keep an eye on them and see if they improve with the new TNF. My physical therapist tries massage for them but so far nothing is helping. I’ve also tried heat, ice, NSAIDs, and a tens unit at home to try to help. I’ve had them for at least a year but they are getting worse. Does anyone else have these or get these and what do you do to help with them??
