I was in hospital because i first went in for a 'bladder infection'. Then, the other half had to ring an ambulance because I was shaking violently and sweating profusely the next morning (for me to drip with sweat is a big deal, I never get more than a little clammy). Turns out I had a kidney infection and my right kidney was double the size of normal
Before that I've been in so many times it's like a second home.
