What does it mean when your lower stomach is a little sore after your first pee of the day ? is because it was held because i was sleeping ?

See professionals...: Does it happen occasionally or consistently? If occurred sporadically, resolved in a short time, and not affecting your daily living, leave it alone. Holding a big amount of urine overnight may cause what you have felt. If so, what not trying to cut down drinking before sleep or just get up to void once by setting an alarm clock to see if that makes difference. If so, you get answer. See doctors.
