I was in a pretty bad car accident a few years back and I had lots of surgeries done to both of my ankles and feet. It is still hard for me to stand/walk/run for long periods of time, but standing is almost the worst. I also need to periodically put my foot up to reduce the swelling since I still have issues with that. In the past years I've taught mostly from my feet, but definitely had down time where I could sit and some time when I could put my foot up. The problem this year is that a) my principal walks to our classrooms every day and b) all my classes are back-to-back. Twice now he's come in while I'm sitting, once while I had my foot up, and I'm worried he's thinking that I'm lazy. Because of that I've been forcing myself to stand during the entire class for all my classes and my ankles are just not happy about it. In fact right now I'm doing all of the RICE letters plus ibuprofen. There's no way I can make it through the year like this. I'm going to buy myself a stool so I'm not completely sitting down, but I can still rest, but I'm wondering if this is something I should write about to my principal. He asked me about my foot when it was up and I told him quickly I've had multiple surgeries and need to put it up sometimes, but it wasn't a full explanation. This is my first year at this school and I really don't want anyone to think poorly of me. But I also don't want to randomly send an email that isn't needed. So thoughts? If I do send an email, what should I say? Thanks!
