I'm hoping to put you in touch with someone experiencing a similar condition. He's dealing with numbness of penis & scrotum from a herniated disk. Numbness & tingling? Maybe not as similar as I think. The original post isn't current but latest is. Plus others will be along to give you the benefit of their experience.

Here's the link to the forum, then look for the thread:
