I hurt my lower back doing Romanian Deads yesterday. I was in the ER until 2 am on a morphine drip, the pain was that bad!! Anyways I'm on my last week of 50 mg EPI, and I absolutely need the pain meds they gave me!! I am on N2 guard and liver longer. Any suggestions on this situation? Mainly worried about liver.. Im on 5mg perc/325 aceto for my pain. Flexeril for muscle relaxant.
