Besides covering my face, I found a warm or hot compression
(hot water bottle) on the area helps the "pain monster" clam down. or if not on the area , I put it on back of head neck to calm /warm the nerve up if possible.
I know others find a cold compression helps or caspin?? cream that is like hot/chilli pepper cream can help .
I hope others will be by to offer some advice.
Most of all I hope you have a day with low pain.
PEACE
