hi Fred
you could have a UTI, have you seen a doctor?
the Stain, could be just a pigment change

hi
thanks a lot to reply.
i had a simple urine check up and it showed blood in urine, probably because of 3 mm kidney stone.
but no infection was detected.
also, i notice 3 tiny rush at head of penis that disappeared after applying some honey on it.
no, have not seen a doctor.

does it get worse without cure?
and i am worry if this colour change be the early stage of cancer
