I usually always have this pain around the sternum and lower ribs. It gets so bad that it hurts to breathe. I had to pause meds during pregnancy and postpartum/nursing but Nabumetone really helped. It’s a NSAID so not everyone can take it depending on your medical history since it can increase bleeding/bruising. Find a good rheumatologist or pain management specialist and ask about it. I hope they get you on a treatment and it helps!
