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.
