Unwelcome visitor

Dear Baxter,
I have an evil visitor called Murgatroyd and don't know how to get rid of it. Everytime I move my arm THERE HE IS.
Love,
An Admirer

Dear Baxter's Admirer,
A little birdie has told me that your unwelcome visitor is a burn on your arm. To help treat burns, you could try fresh aloe vera, or some burn cream from the chemist. Keep it clean and if it needs protection, wrap your arm in a loose bandage.
Love,
Dandelion
