There can be so many reason for suffering from joint pain. I think getting your doctors opinion is really important, maybe run a few tests to rule out anything serious. Many times there is an underlying cause that you wouldn't associate with joint pain.
Of course you could be suffering from arthritis. There are many home remedies for arthritis. One of my favorites is the gin and raisin remedy I wrote about. You can find the recipe for it if you look under "Home Remedies". Then scroll down and look for "Natural Home Remedy for Arthritis". Fish oil supplements are also known to relieve joint pain. Peanut oil is also known to relieve joint pain, just rub it directing on the joint that's in pain and allow it to soak in.
