Symptoms of muscle diseases include abdominal pain, muscle pain and stiffness, involuntary jerky movements, rapid heart rate and difficulty getting up. Examples of muscle diseases include rhabdomyolysis, muscular dystrophy and muscle spasticity, according to WebMD, Mayo Clinic and Healthline. Specific symptoms depend on the particular muscle disease.
Rhabdomyolysis is a condition resulting from a muscle injury, causing muscle fibers to die and escape into the bloodstream. It can affect some parts of the body or the whole body, and symptoms are hard to pinpoint and depend on the cause, states WebMD. Symptoms include rapid heartbeat, difficulty moving arms or legs, urine turning dark red or brown, and pain in the abdomen.
Muscular dystrophy is a condition characterized by loss of muscle mass and progressive weakness. It begins in childhood, mainly in boys, and as of 2015, it has no cure, but therapy and medication can help to manage the symptoms. Symptoms include difficulty getting up, trouble running, muscle pain and large calf muscles, notes Mayo Clinic.
Muscle spasticity results from the damaging of the nerve impulses that control muscle movement, explains Healthline. It can occur due to injury to the brain or spinal cord and diseases such as multiple sclerosis. Muscle spasticity causes symptoms such as back pain, limited range of motion in the joints, abnormal positioning of arms or shoulders, and muscle spasms.
