I am having crunching, popping and grinding noises in my neck and shoulder. There is not much pain in joints but, the muscles do feel tight and painful. I always get urge to stretch these muscles This is on my ride side. Now, my skull and back side of neck also seems to be having numbness or muscle spasm on the right side. There is some pressure in right ear too which gets relieved temporarily when I rotate my head. Is this arthritis causing a pinched nerve or blocking an artery? Can you suggest? Thanks.
