I think what you are feeling in your mouth is where your incisions were done for lower jaw. This is where mine are, as well as the 2 small outside incisions. My mucosa is pretty shredded in that region as well and I think it's a combinasion of incisions and also when my swelling was worse, my mucosa actually came between my teeth and was crushed and also all stuck on my braces (yeah, real fun).
My surgeon pretty much told me that I can now eat anything I can smush between my tongue and my palate and swallow without choking (his exact words). As long as I don't use my teeth, Im good to go. I made some chili today, mashed it with a potato masher (with the cheese added) and ate it with a baby spoon. It was GREAT. This is the first meat I had in over 2 weeks and the carnivore I am loved it! I actually had a second serving and am happily FULL. A weird change from just eating enough to not be hungry...
As far as working out - I usually walk/hike/run a good amount and also do Bikram Yoga and I definitively can't do much still. I can't imagine running right now anyways, with the shock going into was jaw at every step, ouch! I try to at least walk my dog down the street a little farther every day! My surgeon did give me the ok to use 3# weights at this point if I feel up to it, after he said "no to weight lifting" and I pestered him enough to say 3# was fine:) (I figure it is fair game for me to pester him during the 15minutes he gives me a week especially after he makes me cry pulling my sutures!)
I went to the mall today (I should disclaim here that i HATE the mall, but I was desperate to get out with a friend!) and I was doing ok for probably 2 hrs then got acutely extremely tired and crashed, came home and parked myself on the couch. I suppose it's a work in progress and I will slowly make it back to normal.
It kinda sucks though to have all this time where I could go workout and get killer abs, but I can't!
Ennazusie - after 1 week I think you are doing extremely well if you even have a thought for exercise! The dizziness gets better but I seem to have days where it's worse than others - like yesterday, every time I got up, it would go all black for a few seconds, had to wait it out before moving. Today, no episodes.
Oh, how I took for granted how great it feels to be full!
