There are several applications for this medication. It is most widely used to treat rheumatoid arthritis; osteoarthritis; ankylosing spondylitis, which is arthritis that affects spinal joints; acute gout, periarthritis or frozen shoulder, tendinitis, sprains, fractures, lower back pain and pain and inflammation following dental surgery, as well as pain relief from migraines.
