Hi Doctor
Three weeks ago I was bitten in my bed by a small insect. There were four or five bites which developed into small red marks. Overtime those marks have spread and joined up. They itch and are somewhat blistery but not too much.
The affected area seems to be spreading still.
What would you advise please.
Oh, I forgot to say, I am in china working and going to the hospital is a bigger pain that the rash.

Regards Robert
