I have canker sores in my mouth that show up one day and are extremely painful, the next day they’re gone. I have had teeth chip out of nowhere, and my dentist is stumped. My floaters have doubled. I do not have sores on my head. I have tingling sensations on my head as if something is crawling in my scalp. A short while later, I have a headache that spreads across the top of my head to the base, and right behind my ears. It will be 2 years at the end of December.
