1 I've been working on a databse that I can use for myself that will allow me to track things like high blood pressure, blood sugar, mediations, exercise, meals and foods. Answer.

The medications used to treat arthritis vary depending on the type of arthritis. Commonly used arthritis medications include: Analgesics. These medications help reduce pain, but have no effect on inflammation. Examples include acetaminophen (Tylenol, others), tramadol (Ultram, Ultracet, others) and narcotics containing oxycodone (Percocet, Oxycontin, others) or hydrocodone (Norco, Vicoprofen, others).
Pain relievers can make you feel better, but they're not going to change the course of your arthritis. Disease-modifying anti-rheumatic drugs (DMARDs) can actually slow joint damage in people with arthritis from an overactive immune system such as rheumatoid arthritis and psoriatic arthritis.
