postoperative pain
"I got this drug post surgery twice and it had little to effect on my pain. Unfortunately I had forgotten to mention before the second surgery that it failed to work the first time around. Both times I awoke from surgery in tears and severe pain. Only after convincing them I was awake enough for them to take out the tube in my throat, aka using all my strength and energy to hit the side of the bed and staring straight into the eyes of anyone who came near me, was I able to request a different medication for my pain. Immediately upon switching my pain decreased. May be unique to me as I've also heard very good things from others."
