among a lot of other pain meds, the patches are costly, but my rhuemy gives me samples & coupons that help a lot. i use them for both hips due to major burning & pain during the night. they hurt during the day but not that much. anyway, they r a miracle for me. i tried to elminate some of my other meds but i have to take all for everything to be effective. sometimes i try not to put the patches on and sure enough the burning at night is unbearable. so, now i put them on everynight, with skipping just one night to save on money. good luck they're worth it.
