When i urinate, why does my navel hurt?

Here are some...: Does such navel hurt occur every time at either bladder full or empty or just while bladder is really full? How long has it been and how long may it last? Have you had other possibly related symptoms? Clinically, this hurt is considered as a referring pain, which more likely occurs during / soon after peeing to empty a really full bladder. More? Seek evaluation & counseling.
