What would be helpful is if you tell us the medication and body pain described where and like what it feels like (electric shock, like bruises, like stiffness, like tension, etc.). I would guess it is actually a case of your bipolar med not working properly as chronic pain is actually pretty common with bipolar disorder. 1 in 4 have chronic pain with their disorder. Many with bipolar have intense/increased pain sensitivity. They really feel it a bit more than others.
