Pain
"My doctor just switched me from 30mg of MS Contin to hysingla 20mg once a day. Mind you I have been taking the same thing for over 4 years. This hysingla is a joke!!! After 3 hours I was in so much pain I thought I was dying!! Felt like I was going to be sick, and not from the medicine, it was because I was in so much pain. Whoever said this lasts for 24 hours is completely ridiculous. Worst ever!!"
