<s>[INST] Years ago I got kicked in the groin. It busted my left scrotum and today, it is painful and the sensitivity is mostly gone in the head of my penis. when I am with my wife I have a medium erection but when I penetrate her it dies. I am 67 years old with 4 stints in my heart [/INST] HelloScrotal injury need immediate medical attention.You need proper clinical examination and investigations.Investigations include ultrasound and colour doppler of scrotum.Ultrasound can exclude many conditions like local hematoma,testis injury etc.Treatment depend upon findings.Get well soon.Take CareDr.Indu Bhushan </s>
