After diagnosed with Kidney stone which was just 1 inch away from reaching bladder. I have this irregular throbbing or piercing pain on the tip of penis. The pain passes from tip to testicles and from testicles to lower abdomen. Recent ultrasound found just few 2-3 mm stones. However I am taking a homeopathic medicine berberis vulgaris and norflox. KFT tests showed normal functioning and Urine cultures showed no infection. I still have that tingling pain on the tip of penis which increases or decreases during the day. What other problems could it be ??? Prostatitis ?? Or something else. ??
