The first is on my left cheek, near sideburn. The second is on my left shoulder blade. Ive had them since at least 2006. Sometimes they get worse and sometimes they improve. Typically crusty and will bleed if scratched.
They look like patches of eczema. Try buying a 1% hydrocortisone cream from chemist /pharmacy and use on them every day for about a month. That may help. Do try not to scratch…you could introduce infection.
