Private area

I think I hit a nerve while I was masturbating. My leg and arm go numb sometimes when I go to sleep at night and my leg goes numb when I run. Also I have recently been having headaches on that on side of my body(the right). Can all this be caused by hitting a nerve down there? I have a pinched sciatica nerve in my lower back. Ive been having pain down there for three months now. I went to the doctor four times. I keep having UTIs and Yeast infections. :(
