I'm a 65 year old female I take Cymbalta 60 mlg. 1per day, I also take hydrochlorothiazide 25 mlg. daily for high blood pressure 1 per day. I have chronic hepatitis C, very small kidney stones and , I'm allergic to Codeine, Bactrim, & Tributalene. Is there any drug interactions with the medications I'm taking. I also have spinal stenosis, arthritis in my spine. I lifted something heavy and I'm having back spasms & pain. I'm supposed to take Baclofin 10 mlg. 1 tablet at night, should I worry about any drug interaction etc. Thank You
