Off to the docs, but mum suggested the same thing Kim. Slap face? Or something. It's now covering both of my cheeks.

She said it's harmless for normal people and doesn't need to be treated as it goes away on its own but can be dangerous to people with low immune systems. This is a concern as DP's Mum is terminal (cancer) and it could be dangerous if she catches it. While I haven't been to see her while I've been ill (standard for any of us who have contact with her), I have been with DP and he has been visiting her daily. He hasn't shown any symptoms of sore throat/cold yet but there's no way he could avoid catching it. I moved my appointment forward and will check with the doc.
