It is horrible isn't it. I found a mix of things has really helped. Hope some of these are useful.

Meditation - For pain and mindfulness. I have found the Calm app amazing, especially Tamara.
Breathing exercises - very, very good with pain. Lots on youtube.

Keep breathing - a nurse taught me this one. When things are painfull, keep breathing. Also breathe out with something painful, eg Spinal Tap.
Coffee - caffeine is good.
Fresh orange juice - think it must be the sugar.
Almost zero sugar diet.
No alcohol.
Drugs - Oxy is ok but not really strong enough.
