Hi sound a bit thick here but ds (4 last week) often has urine problems. We were away at weekend and he did nothing but wee at least every 20 minutes. I know he was drinking often but seems excessive. He is concerned that at the end of his penis is a small ball of what looks like blood is this normal? I have very limited knowledge of what it should look like and not exactly the sort of thing I can drop into conversation with male friends. Any help gratefully received.
