The most common medications arthritis sufferers take daily (often several times) are non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and naproxen (e.g. Aleve, Advil).  The problem is that regular use of these drugs can cause severe gastro-intestinal problems.  The good news is that there are many natural supplements that can really help you heal - not just mask the pain.  Natural anti-inflammatories like fish oil and curcumin (the active ingredient in the spice turmeric) are helpful.  In particular, research has proven that glucosamine sulfate (not necessarily other types), MSM (methylsulfonylmethane), and synovial fluid (hyaluronic acid) are effective.  These are forms of nutrients that your body makes on its own, and they help the body actually to regenerate and then nourish worn-out or missing cartilage. 
 
But here's another simpler solution I highly recommend you try:  stop eating tomatoes.  Yes, tomatoes.  And potatoes, peppers, eggplant, and related spices like cayenne and paprika.  These are all part of a family called Nightshade vegetables (note that sweet potatoes are not included).  Many times a set of seemingly unrelated inflammatory problems in your body (e.g. headaches, GI distress, eczema, post-nasal drip, muscle/joint pain) are caused by food sensitivities.  These are usually delayed-reaction sensitivities which differ greatly from the typical food "allergy" you hear about where someone eats peanuts and can't breathe.  It just so happens that many arthritis sufferers have a marked sensitivity to Nightshade vegetables.  However, you don't need an expensive test to be sure; just try fully eliminating these foods from your diet for 3-4 weeks and see how you feel.  It needs to be a fully 100% (cold turkey!) elimination in order to give you results, but you have nothing to lose in trying it.  Many of my clients discover they have food sensitivities, so don't hesitate to drop me a line if you need more information.
