The treatment of arthritis is very dependent on the precise type of arthritis present. An accurate diagnosis increases the chances for successful treatment. Treatments available include physical therapy, home remedies, splinting, cold-pack application, paraffin wax dips, anti-inflammatory drugs, pain medications (ranging from acetaminophen [Tylenol] and ibuprofen [Motrin, Advil] to narcotics), immune-altering medications, biologic medications, and surgical operations. Pain from osteoarthritis of the knee can be relieved by hyaluronic acid injections. Rheumatoid arthritis can require medications that suppress the immune system. Low back arthritis that is irritating nerves of the spine can require surgical repair.
