constipation, drug induced
"OMG!!!! This is horrible!!! The cramps n bloating are the worst I've ever had!!!  I suffer from multiple pain issues, fibromyalgia, severe neck and back pain with shooting pins and needles with burning down my legs. Due to a failed back surgery. I'll take that pain over the pain I have from Movantik. I have been back and fourth from the bathroom and sat on the pot till both of my legs are numb. Nothing's moving  but I'm having such bad cramps I can't move."
