Hello doctor.Before a month ago a painful lump came in my right testicle which came and went away.Since three weeks I am having pain in my right testicle and from two days even my left testicle sometimes pain a little.I regularly drink a lot of water but sometimes when I drink less my urine seems very dark and smells very bad.Since 2-3 weeks yellow pus that smells very bad is coming out regularly and I do have phimosis.I did my urine test.It was normal but pus cells in bold letters and were 3-4.What should I do and what could cause it?please tell me doctor.
