Myopathies are a group of diseases that cause muscle weakness. They can be inherited or acquired. Some people with OCD experience myopathies as a result of their compulsive behaviors. This can add to the feeling of isolation because people with myopathies often look healthy and have no outward signs of their illness.
The rheumatologist is the doctor who specializes in the diagnosis and treatment of diseases that affect the joints, muscles, tendons and bones.
Remember that for the proper selection of health professional that treats myopathies you must consider the nature, severity and symptoms you are presenting.
