I have a history of bladder infections. Four days ago I had something of an attack. I had a lot of pain and burning in urethra. Nausea. Pain in the bladder area. In the past four days I have had three attacks. I am taking Cipro. I had all the symptoms of bladder infection frequency, urgency, burning pain when urinated, sometimes I could not urinate at all and it would just hurt so bad. Then on day three, after my last attack, there was a lot of really red blood in toilet. Still blood but becoming less and less. Could this be an infection? or Possible kidney stones?
