Answer
Hi,
thank you for your question.
You need to see a vet with your hamster as soon as possible. Diarrhea is a very serious problem with hamsters and other small rodents, it can kill them in a matter of days.
The itching may be caused by mites, fleas are rare with rodents, although not impossible. The vet will be able to help you with this, too. Over the counter-medication that can be bought in pet shops is usually expensive, useless and possibly dangerous.
I'm sorry that I cannot be of more help to you
