Had it for a day or two. Feeling pressure to wee and burning and stinging towards the end and the need to squeeze more but can't. Had a tummy cramps too. My wee looks rather cloudy and I've been drinking lots of water etc and cranberry juice. I am meant to be going away Monday :-/ can I but anything over the counter??? Tried ringing docs yesterday and as usual pointless as cannot get through. Feeling sore.
