I had a fall which left me with a hairline fracture in my pelvis. I am in physical therapy and my medications are hydrocodone/acetaminophen 7.5-325 T for the fracture, and Gabapentin 300 mg. for a pinched nerve in the leg on the opoosite side. However, I still have debilitating pain in that leg.
Hi I am Chat Doctor. .  In my opinion your medication is fine you may add hot massages with topical gels and some B12 vitamin supplementation will be helpful in most of the cases. Physiotherapy sessions and spinal straightening exercises have a good rule in maintaining your low back pain. Avoid overweight, vigorous movements, heavy lifting, bad sleeping or sitting postures, standing for long time.  If your pain persists ii suggest MRI on spine to rule out any kind of spinal injury like disc or herniation and follow them up with a neurologist for proper evaluation and management.
