A contusion is an injury from an external blow or impact that causes blood vessel damage in the tissue. This results in swelling and pain. Wrap treatments using the liquid for external use "Retterspitz Äußerlich" help reduce swelling more quickly and significantly alleviate pain. The wrap should be left in place for an hour and a half. You can apply up to five wrap treatments a day. The recommended wrap size depends on the affected area of the body. Massaging the muscle treatment "Retterspitz Muskelcreme" into the area further promotes the healing process. Use a line of cream approx. 5-10 cm long. Retterspitz Muskelcreme is extremely skin-friendly and does not contain any diclofenac or ibuprofen.
