Research things that could help you with your RA and neck pain for the time being. Start exploring a good rheumatologist and get some help. Hugs to you!

I have neck pain. X-ray and MRI showed osteoarthritis. Physical therapy helps.

Heat is the best for my neck aches. I sometimes take a muscle relaxer at bedtime when it’s real bad.

I have used a Posture Pump Disc Hydrator for years. It works!

Maybe you should have an MRI done of the neck. It could be disc problems. On top of RA, I have degenerative disc disease. My neck and back hurt all the time. Some days real bad and other days tolerable. I’m sure the RA doesnt help.
So sorry you are in pain. “hugs”
