Woke up to burning sensation on face but it's not hot to touch.

Watch out for early: Shingles - now, you're kind of young for that, but an early sign of shingles outbreak (reactivated chickenpox) is a burning/tingling sensation. So look for a red rash with small raised bumps to develop. Otherwise see your primary care doctor on monday for a closer look. Take care!

VisualDx: Hi, it’s hard to say without a picture but there is a great app that may be able to help you get a diagnosis without being seen in person by a dermatologist. The app is called VisualDX and is one of the best, if not the best out there. Many clinicians, including myself, use it. Just snap a photo and it gives you a list of possible diagnoses. Good luck!
