Karen, honest to god, if it were me I'd be ballistic by now. Yet you persevere, because that's what you have to do. Know that I'm thinking of you and pulling for you. If I could look at your feet and dx your AS, I would.
OK. I've done all that.
I say: Your feet are a mess and you have AS. Will that wash with your doc for an anti-TNF?

You're a fighter, my dear. I know you'll get through this. My shoulder is yours, if you need it, to help bear the load.
Warm hugs,
