Hi, I experience back pain daily because I have scoliosis and recently I feel alot of pain on the lower left side of my back. I take prescriptions cyclobenzaprine and naproxen for back pain as I need to but I don't see any relief on the lower left side of my back. Could this mean that it's kidney related pain? I don't know what to take for such pain. I'm seeing my doctor next week but I'm in so much pain that I end up crying. I noticed something strange which is whenever I drink either orange juice or apple juice I feel much better from pain. I do know that it's vitamin C and that vitamin C fights infection. Could this mean that my kidney is infected? My lower back felt very warm by touch. Orange juice and apple juice is the only relief I have right now. Please let me know.
