Sounds as if you have flu coming on.....keep warm, take paracetomol, get lots of sleep and drink plenty of fluids, hope you will feel better soon, take care sweetheart. X
Oh no that's no good! If you are worried, give NHS Direct a call: 0845 4647. They are really lovely and will put your mind at rest whether they get a Dr. to call you back or come out and see you.
There's a sickness bug on it's way round here. Often happens after a really hot spell. Drink plenty of fluids (not coffee!) and don't overdo it! Lets hope it was caffeine overload!
