I have had no signs of a bladder infection but that's happened before and I was feeling sick and my doctor said he wanted to test me for a UTI and I swore up and down I didn't have one and i definitely did. I had one so bad there was blood in my urine and I had no idea. He gave me medicine and that was the end of it. Today I woke up and my insides hurt. It feels like someone used my guts for a punching bag. It hurts to move certain ways and I was wondering what the signs of a kidney infection are. I've also been feeling like hell and I've been extremely nauseas to the point that I can't sleep.
