Jessinthewilderness,

Welcome to NeuroTalk.

In my opinion and experience, all of the recent events combined to trigger a relapse. The drinking and concert combined with your history were enough to set you into a downward spiral of a return of symptoms.

Headaches can be triggered by too much stimulation, anxiety, or a subtle trauma to the upper neck or a combination of the three. Cognitive rest is basically a respite from stimulation. The concert was the extreme opposite.

I suggest you get some quiet rest and seek a physical therapist or gentle chiropractor to see if your neck needs some treatment. Sleeping and resting with a good straight head and neck posture will also be important.

Many of us have learned we need to moderate activities like concerts and drinking to give our brains a break. We may be able to tolerate one activity but not two or three. You need to find your tolerance level. It may affect you for some time before you regain your tolerance.
