I had a herniated disc and severe nerve pain. I took 16 ibuprofen a day, 4 200mg pills every 6 hours, it did nothing that I could tell. I also used a methylprednisolone dose pack, also didn't seem to help. I also tried prescribed opioid (tramadol), didn't seem to help much.

Acetaminophen worked far, far better than all these. It worked so well, but i wanted to be careful to limit myself to 3000mg a day, so I took 1 500mg pill every 4 hours for a few days while awaiting surgery. It's the only thing that got me through it. Even a epidural lumbar steroid injection didn't help...
