I feel something moving inside of me and it hurts, It causes pain in my left foot and leg, sometimes it cases pain in my chest. Could someone please help? Does this come from masturbating or sex? What can I do to treat it? Is there a certain medicine I should take? Please help, my life has become very gloomy and painful because of this. I'm 23 years old. I'm really normal and smart, I respect girls and they respect me and enjoy casual talks with me. Either way, I still need answers. Please help, thanks.
