I have a pain in my lower right back that goes through the top of my right hip and radiates down the front of my right leg. The front of my right leg is numb, tingly, and extremely pained. this came on all the sudden with no real prior history of back pain. It has gotten consistently worse over the last week in spite of the steroid perscription that I completed. ice helps but...creams sucha as bio freeze... help but... took a muscle relaxor twice. helped but.... nuproxin tried and helped... my pain level just keeps going up. The xrays show a kidney stone. could this be the cause or???????????
