I am sorry that the first two doctors you’ve visited were unable to help you, although my advice to you is still going to be to see another doctor. If you tell them how long you’ve had this problem they may be more inclined to consider your problem more than just a simple allergic reaction, although in all fairness that is probably what it is.
It is possible that the remedies that the doctors gave you did not work because the source of the problem still exists. Perhaps your soap, or shampoo, or the laundry detergent you use with your pillow cases is causing the reaction. Perhaps you have a cat that sleeps on your pillow when you’re not home.
Try changing all the things that you use on your face and head area. If that doesn’t work, or you want to try something even quicker, try moving out of your home for a week and see if it clears up.
I hope that I have been of help.
