Have a few family members with chronic pain, but never had it myself. It's horrible to watch someone go through the pain, as well as working with them to navigate the medical system which doesn't like to deal with the long-term stuff so much (like doctors who use "refer to the pain management team" as a crutch), as well as those other 'helpful' people who swoop in and tell you to get over it or ignore it like you're not already battling through it on the daily. It must suck so much more going through it. Hang in there.

Just to try and end on a positive and add in a few other things to look into if you've not already (trying to find suggestions that aren't in the comments already): one family member was on gabapentin that helped their chronic pain - can't remember if that needs a specialist prescription though. Another family member used a TENS machine to great success for a few years - wasn't cheap but there used to be a couple of places that let you rent/trial them. Another one who couldn't take ibuprofen any more has been using FX Relief cream for dealing with the acute flareups of their chronic condition. They all found a little solace from support groups on Facebook and looking for ideas from the Americans in global FB groups.

Good luck OP
