The past three to four months I have been having arthritis type pain soreness in my upper arm and shoulder ball joint area of my left arm. I'm not taking any medication. I've only use rubbing alcohol. The pain has not gotten any worse it's more consistent but it has not gotten any better either. There are no medical issues in my family that I'm aware of besides some family members do or have had
diabetes. What could be the cause of this issue and should I seek medical attention.
