Hi, I am getting a red rash on the collar bone from time to time, it is itchy and feels like a sunburn sensation, I have stopped wearing prefum and necklaces as I thought it cames from this but it keeps coming back.
I have just had some noodles and chicken for lunch and as I just came back to my desk, have realised this itch and burning sensation again, could this be a food allergy?

many thanks
Christelle
