I've had ES for almost 15 years now, although i've only recently been diagnosed with it.
I've been on Norspan pain patches for about 8 to 10 years now. I'm on 10 mgs.
The patch is effective for 7 days, & then you put a fresh patch on.
Patches have helped massively with my ES pain.
Occasionally i've forgot to put a new patch on after a week, & the pain has suddenly got worse, & i wonder why... then i realize that i've forgot to put a fresh patch on.
I've foud patches to be really good, the only downfall is that they're addictive ( being opoid)
I've chose to have surgery & am currently waiting to hear when my operation will be.
Heat packs, i've found help with the facial pain & migrain due to ES.
I hope i've been able to help you somewhat.
