I remember years and years ago, having psoriasis in my nose. It was very painful and uncomfortable.
I told my doctor this. He firmly said, "You can't get psoriasis in your nose. I was very naive and in my mind, if that's what the doctor said, then it has to be true.
I would just put Vaseline in the nose to get some comfort, and whatever creams the doctor gave me for my skin. I don't remember how long I did this, but it eventually went away.
Back in the day, I would never have dreamed of not believing a doctor. It's been several decades now. But in today's world, If I'm not sure; I will get a 2nd opinion.
Have you ever doubted your doctor or questioned them? If so, did you take any necessary steps?
