did that chiro do any positional testing to rule in/out if it could be from cervical or T spine?
traction/compression, tilting of head to find if pain increased or no changes...
that sort of thing?

Of course you have have both TOS & spinal stuff , sorry but it's possible...
thus makes for a more complex case..

Just a note that too much of any over the counter med does have effects also

I messed my tummy & gut up from too much Advil/Motrin when trying to keep working... sensitive tummy and minor IBS....
so be careful, I had no clue back then and did not do a search on it.

stress & tension does aggravate things.
we tighten up and breath more shallowly - work to relax & do deep diaphragm breathing.
