Hi there i have just woke up with really itchy pubic are and a bad headache, i needed a wee so went upstairs to go, upon finishing i stood up and started to sweat out and the next thing i know my wife was getting me up off the floor. 5 mins later im shivering (shock) im guessing... but what would bring this on like that, im 37 fit non smoker and a occasional  drinker... and normally play a lot of sports but not at mo as i have a sore back..
