There is a fibro pressure point that we check that is just below the collar bone. Very painful area and iften swollen. But agree with Sylvia to get it checked.

I have problems like that,get it checked out before you do anymore exercises darling.xxx

Definitely a possibility that could be RA. I've had my collarbone hurt, jaw, shoulders, knuckles, feet hurt at some point during my diagnosis. Don't rule it out, present it to your physician.

RA pain can hit almost anywhere. You can hurt in places you didn't even know you had.

I have terrible pain in the clavicle area. It’s RA
