I woke up to this just this morning. No pain, itching etc… This is the back of my head. Laid on my memory foam pillow as usual. The only thing that was weird was I woke up in the middle of the night and had numbness in my head like It was pinched and my head fell asleep and could feel the blood rush back to my head. Not sure if that’s connected? But very note worthy I think? Anyone else possibly notice some like that when this happened? Curious
