Topamax and shape

I am on 300mgs of topamax a day for epilepsy, and my side effects are the flat tasting carbonated beverages. But the worst side effects is the feeling in the bottoms of my feet. They feel as if my sox are all bunched up and stuffed between my toes, and knotted up under the balls of my feet. It is a miserable feeling. I get the tingling feelings as well. My wife and I love hiking and I a try to stay in shape by doing 4 miles a day on my treadmill. I am 60 years old. I have to really push myself mentally. I hate this feeling. I don't mind the flat tasted, as I can do without the carbonation anyway, but the feet stuff has got to go.
