So for the last month or so my skin has been very itchy, all over my body.

Doctor says it's a reaction to something, but impossible to find out to what. He did a blood test, only a slight allergy to dust mites...

Same thing happened to my colleague (much worse) at around the same time. He has a lot of allergies and health issues. Don't know if it's related...

Any ideas? Something i can do to stop/prevent it? I'm now taking an anti-histamine once every two days, that takes the itching away.

My doc says it will go away over time... The thing that annoys me most is not knowing what caused or what is causing this...
