Was about to comment the same. I had a severe headache this week, the second headache episode for this year. It's not chronic so it's off-topic, but I was wondering if the reason headaches are not catalogued here is because pain management clinics don't handle them.

This is probably due to their definition of chronic, as migraines and headaches are usually episodic.

Yeah, it's odd to see that omitted, especially for headaches that are related to muscle and joint issues.

Or trigeminal nerve pain.
