I had to wear a mask when I was out in public for about 2-3 months after my transplant (2024). The only time I wore it in the car was if I was gong from one store to another maybe a quarter mile down the street. I would just put it under my chin instead of taking it fully off and on. In the supermarket if I got a look,I would tell them that I just got a transplant so they didn't think I was a nut.
