I'm so sorry about your pain, but I'm glad you found us. I'm fairly new here and I have found some very caring and non-judgemental folks on this forum.
It sounds to me like you are way under-treated for such an injury, but that's just my opinion. If you are not getting relief with your current med regime, I think you should talk to your doctor (hopefully you have a primary care physician...or PCP as you will often see here) and ask for a referral to a pain management physician. I have been treated by my PCP for about 5 years for my back pain issues, but I finally got to where my current meds are no longer relieving my pain. I am now awaiting my first appointment with a pain management doc, which will be on the 29th this month. I think this will be your best option. If you don't have a recent MRI, I would encourage you to ask your physician for one, so that you can have it available for PM if you do see one.
Good luck, Josh, and I hope you find some relief soon.
