Can drinking soda cause pain in joints especially on foot?

Soda deffinately adds to pains of the joints. It deteriates bones and dehydrates you making the joints stick rather than glide, plus I think that carbonization does something too. You didn't say how long you've been drinking soda though so it's hard to say if it's possible that it's done damage or not.

I found a quick article about this. Couldn't find the one I remember reading that said soda might reduce your bodies' ability to absorb calcium.

Oh oh. I have been drinking way to much Dr. Pepper for about 2 years now, and the tops of my feet are always painful. I tried stopping and cut down to one a day and it has been a little better too.

you might be developing GOUT. You do not want gout. Look into it

The doctor will use a big needle to suck out fluid and look for crystals which gout is and that is how they test for it. Thecrystals can be difficult to find, so it may take several tries. After that, your put on medication for life, but it's worth it casue the swelling and pain never comes back. The diet will not control the gout. Yes, it's a lethal disease.
