Polymyalgia is a chronic disease, which means that it has no cure, according to Medscape. Regular treatment involves a course of corticosteroids, which may provide relief for up to a year and place the patient into remission, states Mayo Clinic.
About 10 percent of patients who finish corticosteroid treatment relapse within 10 years. Other treatments being studied for use in polymyalgia patients as of 2015 include immune-suppressing Trexall and anti-tumor necrosis factor drugs that reduce inflammation. These drugs may be used in lieu of corticosteroids, as long-term use of corticosteroids is linked to severe side effects including cataracts, obesity, diabetes and high cholesterol, according to Mayo Clinic.
