Yes, about
once or twice a week. I usually wake up with it, occasionally, it appears after a particularly stressful, physically active day. The tylenol with codeine seems to do nothing. I have to take a medicine that works at the neurological level. I use a small dose of amyltriptilene (25 mg.), and lie down with a bed buddy or heating pad or both. Some days all I can do is curl up in the fetal position and stare the pain down. Usually within 24 hours it will pass.
