pain
"I take Oxycodone HCL for Fibromyalgia CFS/ME
four times a day at 20 mg it really helps my breakthrough pain I'm glad to have it I also take Hysingla ER 100 mg I don't really get what the Hysingla is supposed to do if there is expected breakthrough pain? I'm still trying to read about it  Thank god I have Oxycodone to help me be able to function I haven't had any severe side effects that I couldn't handle the one I hate most is the constipation it makes me ill I get nauseous and pain in my side until it's taken care of"
