I've been on flexeril and neurontin for over a year, why am I not getting better?

From what I have read of your condition you are not on the correct medication. I am surprised this is all you are on. Here is what I found:

Polymyositis - adult Symptoms

Polymyositis is a systemic disease, which means it affects the whole body. Symptoms include:
•Difficulty swallowing
•Muscle pain
•Muscle weakness in the proximal muscles (shoulders, hips, etc.) that makes it difficult to raise the arms over the head, get up from a sitting position, or climb stairs
•Problems with the voice (caused by weak throat muscles)
•Shortness of breath

Patients may also have:
•Fatigue
•Fever
•Joint pain
•Loss of appetite
•Morning stiffness
•Weight loss

A similar condition called dermatomyositis causes a reddish-purple or red rash on the face or body.

Tests and Exams

Muscle weakness and tenderness can be signs of polymyositis. A rash is a sign of a similar condition, dermatomyositis.

Tests may include:
•Autoimmune antibodies and inflammation tests
•CPK
•Electromyography
•MRI of affected muscles
•Muscle biopsy
•Myoglobin in the urine
•Serum aldolase

Patients with this condition must be carefully monitored for cancer.

Treatment of Polymyositis - adult

The main treatment is with corticosteroid medications. When muscle strength improves, usually in 4 to 6 weeks, the medication is slowly tapered off. Maintenance therapy with prednisone may be continued indefinitely. In people who fail to respond to corticosteroids, medications to suppress the immune system, such as methotrexate and azathioprine, may be used.

Intravenous gamma globulin has been tried, with mixed results. It is too soon to know what role biologic drugs may play in treating this condition.

If the condition is associated with a tumor, it may improve if the tumor is removed.

Prognosis (Outlook)

Response to treatment varies, and it depends on whether there are complications. The 5-year mortality can be as high as 20%.

Many patients, especially children, go into remission (a period when no symptoms are present) and recover. For most other people, immunosuppressant drugs can control the disease.

In adults, death may result from:
•Malnutrition
•Pneumonia
•Respiratory failure
•Severe, long-term muscle weakness

The major causes of death are cancer (malignancy) and lung disease.

Potential Complications
•Calcium deposits in the affected muscles, especially in children with the disease
•Cancer
•Heart disease, lung disease, or abdominal complications

When to Contact a Health Professional

Call your health care provider if you have symptoms of this disorder. Seek emergency treatment if you have shortness of breath and difficulty swallowing.

I hope this helps, and I hope you contact a doctor ASAP about your condtion...
