I have this, but it's from SFN. I have left sided eye, face and throat pain.

When I have a bad flair (which is multiple times each week), I usually try to do some deep breathing to try and relax. I do the deep breathing in a 1:2 ratio. 1 part on the inhale to 2 parts on the exhale.

If I'm at work, I will take a 10 minute walk to try and move to get my mind off of it.
