chronic pain
"I have many spine health issues and as a result, experience the joys of chronic back pain.  This medicine works well for moderate pain for me.  I did build up a tolerance for it pretty quickly, however, which is typical for any pain medicine.  

Bad side effects I experienced were debilitating nausea and hot flashes when it was taken on an empty stomach.  Also, the all-over "itchies," when I first started taking the medicine.  Both of these can be prevented by eating with the medicine and taking an antihistamine with it."
