3 - 4 times a week I have symtoms of all, legs ankles toes elbows,fingers shoulders,hips,etc., hurts. I test positive for osteo arth. but negetive for all other arth. I have had tests by specialist but nothing turns up. The only thing that seems to help is 15 mgs of percocet and 1 1/2 hours before it takes effect. I have noticed it only in the afternoon or evening.
