I feel pains in finger joints , is it arthritis? what med should i take n foods that i will avoid?

It might be.: Certainly the more joints that are involved, the greater likelyhood that it is some form of arthritis, especially if it has gone on for weeks. I would advise you, because of your age, that it is unlikely to be degenerative, and may be inflammatory. I advise seeing your physician, or seeing a rheumatolgist! i also favor once daily nsaids, for example Meloxicam 15mg. You need an rx for this.
