arthritis / lupus or mixed connective tissue disorder?

Hi, welcome to the ehealth forum and I am glad to help you.
Mixed connective tissue disease (MCTD) is an uncommon autoimmune disorder that causes overlapping features of primarily three connective tissue diseases i.e. lupus, scleroderma and polymyositis. Mixed connective tissue disease also may have features of rheumatoid arthritis. Indications of these diseases usually don't appear all at once, which complicates the diagnosis of mixed connective tissue disease. People with mixed connective tissue disease often are first diagnosed with lupus. As the disease progresses and other signs and symptoms become apparent, the diagnosis is updated.
There's no cure for mixed connective tissue disease, but medication can help manage the signs and symptoms of the disease.
The type of medication prescribed depends on the severity of your disease and the symptoms you have. Medications may include corticosteroids, NSAIDS and other immunosuppressants based on your signs and symptoms.
Living with a chronic disease that has no cure can affect your life in a number of ways. To help cope with your condition, you can eat a balanced diet with plenty of fruits and vegetables. Exercise to the best of your ability. Find ways to relieve stress, such as meditating or listening to music. Staying healthy may ease your signs and symptoms or help you deal with them better. Social support helps you cope with the stress of mixed connective tissue disease. Ask your doctor about support groups in your area for people with chronic illnesses.
Hope this helps. Take care.
