What it is
Dermatomyositis in adults is sometimes linked to cancer, so screening tests are usually done.
Steroids and other medicines that calm the immune system, plus exercise and physiotherapy, help most types.
Common signs
- Weakness in the shoulders, hips and thighs
- Difficulty climbing stairs or lifting the arms
- Muscle aches
- Tiredness
- A purple or red rash on the face, eyelids or knuckles in dermatomyositis
How it is usually diagnosed
- Blood test for creatine kinase and antibodies
- EMG
- MRI of the muscles
- Muscle biopsy
Records worth keeping
Keeping these together makes each appointment easier, especially when you see a new doctor:
- Creatine kinase results over time
- Antibody and biopsy results
- MRI reports
- Rheumatology or neurology letters
Questions to ask your doctor
- Which type of myositis do I have?
- Do I need cancer screening?
- What exercise is safe for me?
