Mine started in November of 2021. Only on my left side in side breast area. I started getting bumps clear down my left side rib cage. Now it’s both sides and is beginning to work it’s way around my back. At first I thought it was a breast lump. I had a mammogram and it showed the my lymph nodes were inflamed. Then they ordered a chest X-ray, then an ultrasound and determined it was a fatty tissue. Then they referred me to a general surgeon to see me about removal. The surgeon after he poked said he thought it was the cartilage between my ribs and around my sternum was inflamed. He put me on a medrol dose pack. That helped for a couple days. The pain got so bad I ended up in the ER. They eliminated a couple more things but determined nothing. I’m now in so much pain 24/7. Sometimes it feels like I have a tourniquet around my middle and it just keeps getting tighter. Sometimes it is just a stabbing pain. Other times it feels like someone has been standing on my ribs. I’m only sleeping a couple hours a night because of the pain. I’m tired, frustrated and just want it to stop. Thank you for your responses. God bless you.

Yes it happens on one side of my collar bone.

yes. flares of this come and go.

I’ve had what feels almost like a bruise under my left breast. I’m so short, everything is just all smashed together. 🤣 What does yours feel like? I don’t know if mine is what you’re talking about, I thought RA systems are bilateral.

I find that anywhere I broke or had serious injuries I have RA attacking. So, basically everywhere. It is constant, but moving might really hurt... it pays off. Depression is a real problem when you give in to RA pain.
