not that great for fronzen shoulder problem [SEP] i tried this for a frozen shoulder problem after reading some online medical sites that this may work it does not really help a lot but i do notice some relief i have a bit more flexibility in my arm and can do the proper exercises more easily than without using it but i have to apply it every six to eight hours i found that horse liniment worked a lot better as i would only need to apply that twice a day however the liniment smell is strong and the rose scented dmso cream is less medical smelling
