I don't know if any of these alternative therapies might help or not, but I know most MDs don't ever suggest them...

Acupuncture
highly skilled & expert & gentle chiropractor (avodiing the sensitive areas)
EFT ( emotional freedom technique)
Hypnosis
expert and skilled bodyworker - like hellerwork or such
TENS or IF stim
low level laser

sounds a bit like a winging scapula is involved - we have posts about that- you can use the search link in my siggy

the purple hands - have drs checked for vascular compressions?
Is there swelling also?


You might find some other helps on our thoracic outlet syndrome (TOS) forum, some of your symtptoms are very similar to TOS.
