Have a blood test and ex ray of the shoulders. Good luck. Try some anti inflammation meds. I take Cataflam.

RA pain isn't always the same. Sometimes it feels like a throbbing pain, like when you smash your thumb with a hammer. Sometimes it's a sharp pain like a bad charley horse. The pain can hit almost anywhere, from your jaw to your toes.

I also experience this but hubby is a an expert at massage it really helps but it mustn't be a deep massage

I get sharp shooting pains too. mostly hands and arms and sometimes toes. I guess it's from the RA.

I do experience that i feel like its because of all the lifting i do, my shoulder joints are extremely tight and sometimes i also have pain in the muscles below my should joints. Im not sure if this is helpful,my wrists burn as well
