I take Mobic and 325 aspirin daily with a muscle relaxer to be able to do my daily routine... I take the mobic in the am and aspirin in pm. I have torn my rotor cuff and will be having surgery next week and the pain has increased to where I am needing to take a Norco 5 in the pm and will probably increase for a short time after the surgery. I want to know what shouldn't be taken together. I also have liver problems.
