Hi, my husband had these ch's for 6 years almost every day with no stopping period until he had surgery on his jaw and for some weird reason they stopped for 7 years. they came back one month ago much worse than before. can someone tell me if this is episodic or chronic and have you ever heard of them stopping from a head injury.
