Can over masturbation be cured?

I am 19. I thought masturbating daily was normal and have been doin it since 4 years. I just started to feel groin pain 4 days ago and ual exhaustion like semen leakage when no and fuzzy visions and eye flickering. I stopped masturbating now and wont do it more than 2-3 times a week. I am very scared that i might have became impotent or infertile. Could this happen? is there a cure that I should not worry about this thing anymore?? Please Help am very scared!
