I honestly have not been following Everlast's posts. And, yes, "Mr Anatomical" was a surprise to see (~ Wright LOL)
Everlast, if you're asking if your symptoms sound like ALS, apparently you've already had this conversation here before, and its been asked and answered more than a few times (and like Barry pointed out in another thread, this is a support forum, not diagnostic forum)
I would like to make a couple of observations. First, that had to be a lot of work making this graphic up for us. Second, if anything, chewing gum is more likely to make things worse for someone who has ALS (I don't know, don't chew gum, like at all) But, even eating sometimes triggers jaw spasms for me, so I'm thinking gum would not improve how someone feels.
Chewing gum
could help as a release for anxiety, or possibly help if there were digestion problems such as reflux and reflux could cause pain there where you have that big red area in the chest highlighted.
Have you been to a rheumatologist? Might be a specialty that could help you.
How about crossing motor neuron disease off of your list and moving on to other causes?
good luck
