We have too. My biggest worry is that my elderly mother has 4 doctor appointments next month. Not sure what to do about that. She has to go but it’s the last place either of us need to be right now.
Wash your hands before you go in, and when you come out of the appointments.
You and your mom should be fine. Unless you are somewhere with cases of COVID you will more likely to get a Rhinovirus.
Be clean, not scared.
Would the doctor be willing to do a phone consult? Surely they understand the risks
