Fluid can collect in the tissue as a result of inflammation, contusions and overstretching. This causes painful swelling. Wrap treatments using the liquid for external use "Retterspitz Äußerlich" help reduce swelling and relieve pain. Apply the wrap treatment one to five times a day, in bed if need be, for one and a half to two hours each time. After removing the wrap, complement the treatment with a gentle massage using the muscle treatment "Retterspitz Muskelcreme". Use a line of cream approx. 5-10 cm long. Retterspitz Muskelcreme is extremely skin-friendly and does not contain any diclofenac or ibuprofen.
