Arthritis responds well to moist heat, and large doses of Opiate painkillers. Had an mri done, arthritis in my back, neck, lower back, hips and knees, shoulders, too. Doctor suspects getting off a motorcycle at 60 mph a few decades ago, caused bone spurs in my shoulder. Hence a prescription for 250 mg/tramadol/day, While I preferred Aspirin, my drug for Stroke prevention, makes me subject to internal bleeding, so I reluctantly take Tylenol.

Take a long hot shower, it will do wonders for you... Of course, you just put up with it, but I suggest you get a dutch style bike.
