i have been taking neurontin for about 3 or 4 years now. i am also on several other meds. verapamil 120mg bid,cytomel 25mg 1/2 tab qd,valium 5 mg 1 tab tid,zoloft 100mg 2 tab qd, levoxyl 0.125mg qd and imertrex 100mg at start of migraine plus more later if needed(which i won't do) recently i have been having a burning tounge. my dr. says it could be one of my meds.'turning against me'. i also urinate all of the time. i can't go anywhere! i also can't urinate if i take almost any psytrophic drugs because i can't release it from my bladder. i have been schizo-affective for many years now. only within the last year have the meds.started to bother me. could the neurontin be the cause of my burning tounge and frequent urination? i already know which meds. that i use to be on that caused the inability to release urine from my bladder. i don't take those anymore? any help would be appreciated. my doctors are stumped. oh yes , my kidneys and bladder are ok i had them checked out by specialist. sorry. my neurontin is 300mg qd.
