I keep getting a sensation of things crawling on my face, no itching or stinging, just lightly crawling all over. what could this?

That is called formication, or a sensation that your skin is "crawling," is a physical symptom that occurs without a physical cause. This symptom is also called a tactile hallucination. Formication can occur with mental health conditions, neurological diseases, or menopause. Due to your age, most likely menopause. As estrogen levels stabilize post menopause, formication should settle down.
