I have been experiencing testicular and scrotum pain from past 5 months. I have done scrotum ultrasound but the report came normal. The pain goes to lower back sometimes and also my testis been hanging. As per ultrasound the blood supply to testis is normal. I am experiencing very low sex drive day by day. If I get arousal or masturbate the pain increases. There is no swelling in the scrotum area but it hurts when pressed hard. Have some constipation issues but that is not really hard. The pain and discomfort is not consistent as sometimes it goes off completely. Urine and blood test report also seems quite normal. Please advise.
