Some of it sounds like RSD/CRPS and some sounds like TOS...

[Ive noticed my speech is a little off & i sometimes struggle pronouncing words (never had this problem ever in my life). I've also noticed i choke more while drinking (like goes down the wrong "pipe" & occasionally have trouble swallowing) poor appetite.
vision has been getting blurry
dropping things, my balance is off, constable tripping
memory is getting pretty bad (I've always had a great memory)
shoulder has significantly "dropped"
golfers & tennis elbow & unstable wrist.

Those sound so familiar.. I had a lot of this early on with my RSI/TOS - due to misalignment's, trigger points & muscle spasms..
It took about 2+ years to recover but now mainly just some minor lingering myofascial symptoms.
And bad weather fronts or abrupt barometric changes affect me & many with myofascial pain and TOS.

Seek the best docs & PTs you can find, or even highly skilled chiropractor if you are comfortable with that..( I had the most help from a DC that also used PT modalities.
If they don't listen don't go back. Call around or email them first and ask questions before making any appts.


Post # 1 in this thread is a crash course of links for TOS, PT/therapies & some RSD links too -
