Teacher misses school today

I have been out sick today with some kind of muscle strain in my neck and shoulders.  I went to a walk-in clinic yesterday and was given medicine, but that didn't make a dent in the pain, so I saw my doctor today and got stronger meds.  He said it's just one of those back-and-neck issues that can happen and we're not really aware of the cause.  At any rate, I'm still battling the pain but I hope to be back at school tomorrow. Tell my students I miss them and am hoping for a speedy recovery.
