Dog skin plaster is usually changed once every 24 hours and is recommended to be used under the guidance of a doctor. The main effect of dog skin plaster is to relax the tendons and activate the channels, dispel cold and relieve pain, activate blood circulation and remove blood stasis, which is applicable to pain diseases caused by various reasons. Such as pain caused by bruises, pain caused by lumbar disc herniation, pain caused by degenerative disease of bone and joint, pain caused by sports injury, etc., can be treated with dog skin plaster. Local hot compress or physiotherapy followed by plaster can accelerate the absorption of drugs, which can well relieve pain and shorten the recovery period. In addition, patients should also pay special attention to the allergic reaction of the skin when applying. Some patients may experience skin allergy such as skin flushing, itching, papules or blisters, which generally require no special treatment and can be recovered after 3-5 days of discontinuation, while those with serious symptoms need to go to hospital for treatment.
