sounds similar to what i am experiencing. can feel mines really long. i experienced muscular cysticercosis a few weeks ago, but a large tape worm is still wrapped all over. only praziquantel seems to act on it for a few hours.
it's most likely Taenia Solium but only worm recognised by medical literature to exist in gums is gongylonema. deep canal dug out on my gums, beginning to hurt during sleep, waking me up multiple times.
Do email me to share if you've experienced anything similar. i will share the info with the specialist I'm seeing
