I was diagnosed 14 years ago, but pain didn’t start until roughly 3 years ago.
Used to be in severe pain all night, every night ! 16 meds have failed to relieve it so far and the only thing that has helped has been my own education & changes to my mental approach.
It doesn’t clear all pain every now and then - but it is a damn sight more effective than all the prescription drugs I’ve been given over the years.
The thing to keep in mind is that MS is an entirely personal condition and what works for one person may not help someone else in the slightest e.g. plenty of folk have benefitted from ‘Gabapentin’, but it’s one of the meds that wasn’t successful for me.
All I’d suggest is try different things - get to know your MS - and accept that just because something works for some people, that’s no guarantee that it will also work for you!
Best of luck,
