Hi... welcome... despite it all you sound like you are doing well. I would ask maybe if there are any adjustments that could be made to your teeth. Jaws etc are hard as the muscles involved could atrophy a bit. Maybe keep stretching and working it. As for tongue swelling it could be a number of things... the tongue is a muscle to so you should maybe see physio about exercises to get the blood flowing and such. that may help reduce the swelling. Hugs.
