Renal tubular acidosis symptoms and conditions

I was placed on Topamax, off label, for suspected bipolar illness (now disproven). My cognition, word finding abilities, memory has been so adversely affected that I am now on disability. I had 5 kidney stones due to the development of Renal Tubular Acidosis, nearing renal failure (a side effect doctors don't warn patients about). This in turn led to osteomalacia, softening of the bones, only discovered after I broke all three major bones in my leg and snapped off my foot stepping off the lowest seat of a bleecher. I've suffered tingling in arms, hands, legs & feet (nerve damage), lesions in the brain, muscle spasms, heat & cold intolerance, insomnia etc... Although I lost weight, I gained it back (then some) as soon as I reduced the dosage of 800 mgs. Upon stopping the drug to save my kidneys, thus my life, my kidney function returned to almost normal within a few months, although there is residual damage. All other side affects remain two years later. Losing weight is not worth dying! Beware of this drug being used off label! I would never trust this drug!
