I was taking the drug elmiron for a bladder issue. a few days after taking it I noticed that my groin between my right leg hurt and my right leg felt like pins aND needles. then it went to my tailbone and that had pins and needles. then it spread to my left chest and arm that had pins and needles. then my back. then my right arm. it even went into my face chin lips and tongue. I came off elmiron a week ago but I still have the tingling feeling rotating through my body. am I still having a side effect? how long will I have side effect for?
