I Have Been Taking Alot Of Imodium For A Couple

i have been taking alot of imodium for a couple weeks. I also take ritalin for depression so i get very dehydrated. im starting to have back pain that is moving to my groin and down my leg, im wondering if i am maybe passing a kidney stone. also have very upset stomach, I forgot i also take prilosec everyday and have high blood pressure that has been pretty out of control the last 2 weeks
