Has anyone noticed a flareup of TN pain after sleeping on their side? My TN pain has been pretty much under control since being put on Lamotrigine in Aug/Sept of 2020, with a rare occasional moderate flareup. I usually sleep on my back but this past week I did spend some time on my side, before falling asleep. About two days after this I had a horrible flareup, something I haven't had in years. I would have on the rare occasion, slight pain when rubbing my upper lip or wiping my nose. I have discovered, in the past, that neck positions while laying on my back can affect my TN pain. Of course, my neurologist said that position should not make a difference. Has anyone else noticed possible positional flareups?
