This study of patients who have had a stroke showed where the patients had pain and what it was causing it. Joint pain, in the orange circle, represents 40% of the pain. 20% was mostly in the shoulder. In the green circle, 10% reported headaches. Central post stroke pain (nerve pain or neuropathic pain), in dark blue, was reported at 8%. Spasticity or muscle spasms were reported by 7% as shown in light blue. Very rarely was complex regional pain syndrome reported.
These kinds of pain often overlapped. Finding the cause and treating some of these together can be helpful.
