"i have degenerative disks in l-1 thru l-4, with herniation in l-4, l-5, and s-1. also have nerve root damage, which causes pain radiating to my left hip, left leg, and bottom of feet. i take 2, opana er 20mg tablets a day. opana er works fairly well on controlling my back pain, while it&#039;s not eliminated totally, i&#039;m able to function better on most days with the help of lortab 10 mg for breakthrough pain along with my opana er.
