Symptoms of sciatic nerve pain/irritation generally cause pains which shoot down the buttocks down the leg, burning or tingling sensations in the legs, and cramps. Epididymytis, prostatitis, or any inflammation of the male genital tract, may cause a number of symptoms, Back pain, testicular pain, difficulty voiding, just to name a few. I would suggest some diagnostic studies, to rule out a chronic infection or any other anomaly.
