Dermatomyositis is a disease of the muscles, although its symptoms most often appear on the skin in the form of a rash or inflammation. The areas most commonly affected by dermatomyositis are the face, the neck, the shoulders, the chest, and the back. In addition to the rash, patients may also experience a weakness in the muscles, soreness or stiffness, and swallowing and breathing difficulties.
Medical marijuana may be able to reduce some of the discomfort associated with dermatomyositis. Marijuana may also make to easier for the patient to breathe.
