Does arthritis cause a radiating pain up your arm?

Evaluate Neck. If you are not improving have your doctor order a cervical spine mri. Many times a herniated disc in the neck can cause arm pain especially if you have not improved with the medications and physical therapy. If it is a herniated disc you may need evaluation from a spine specialist to determine what other options might be needed (injections, surgery, etc) to help reduce pain.
Not usually. Arthritis does not usually cause pain to radiate up the arm. Visit your doctor to evaluate for other causes.
