A wrap treatment using the liquid for external use "Retterspitz Äußerlich" helps reduce swelling and stimulates the blood flow. The knee bandage "Retterspitz Kniebandage" is perfect for this. The wrap should be left in place for an hour and a half. Once the wrap has been removed, the knee can be treated with the muscle treatment "Retterspitz Muskelcreme". After applying the cream, the knee should be kept warm. Retterspitz Muskelcreme is extremely skin-friendly and does not contain any diclofenac or ibuprofen.
