Mostly showing up around the neck area, some on my side as well. A bit itchy, not feeling sick or fever.
It could be an allergic skin rash caused by for example your pillows. You can try applying honey on your affected area 2 to 3 times daily. Leave it on for some hours and rinse it off. If this remedy doesn’t help, see your dermatologist. You may have a more serious problem that requires medical attention.
