Any pain relief advice?

I am on day 6/7 of constant migraines and I’m losing my mind! Sumatriptan isn’t working, paracetamol, ibuprofen, co-codomol- nothing is even touching the sides! My preventative, propranolol, clearly isn’t doing anything and neither is Feverfew or Magnesium

Dark rooms, silence, caffeine, cold cap, nasal sprays, anti-histamines, nothing wants to work. The only thing that made the pain go away for a little was alcohol and that is a dark path I don’t wanna wander down!

If anyone has anything they can advise, in the UK (not saying other peeps can’t help but you can’t get certain things here that you can get in other countries) I am all ears!
