No reason to be concerned. It sounds like severe carpal tunnel syndrome or some other nerve entrapment syndrome; get that looked after, as JJ suggested.
Depending on your age, arthritis can also play havoc with fingers.
Hi Kati and welcome,
I'm not sure why you would be concerned it could be a neurological condition like MS and not from a pinched nerve, i would suggest you at least see your GP to confirm what the chiropractor and acupuncturist consider your situation to be caused by.
Hope that helps......JJ
