did this ever resolve? going through the same thing with my 6 year old. No Uti, urine clean, no redness, no abuse.... no answers! Told by the ER its probably related to constipation and shoed away, but its been every night for about a month. EVERY time he lays down to go to bed. Hes soooo uncomfortable.
Is he getting erect? Has he ever maturbated? It is possible that these are the feelings that he is having (and is decribing them as tingling) and does not understand them yet.
