Feeling better but tingling sometimes in hands

Hi Esther, I'm doing good.  My neck feels so much better and my massage therapist was very impressed.  The odd thing though is I've developed intermittent tingling in my hands since I changed pillows.  My chiropracter said maybe it's a pinched nerve or maybe my body is just adjusting to the realignment I'm doing now.  Is this normal?  I think it's strange I'm having relief with my neck, no pain, just this tingling that comes and goes.  I've order the stretchsit cushion for my car.  Hoping it helps.  Should I be concerned or have you heard of this before.  After all I am 59. ;D  Any suggestions would be appreciated.
