Good day to you. For the past three months I have been going through a very rough patch and would be greatly relieved if you can give me a clue of whats going on. As regretful as I am, I had a bad habit of masturbation with very little control. Now when I masturbate, my left leg goes numb and there is no telling hiw many days or months it will take to come back to normal. There is also pain in my scrotum (left side) and perineal. The muscles at the left of my lower spine also hurt. The problem is only at the left side. I was diagnosed with minor scoliosis with annular tear and muscular spasm. Please tell me what is the relation between masturbation and the muscles of my spine/leg. Is something being stretched or something?
