They are saying at Doctors today possibly Ulnar nerve or Carpal Tunnel syndrome as I have been putting a lot of pressure on my wrist recently resting it on my desk in an awkward way and also typing on my notebook...they have advised me to rest it and see what happens...put some Deep Heat type stuff on my lower wrist and it has improved it dramatically but not gone completely
Although just before it started I had pulled a muscle in the opposite rear left side of neck and shoulder blade area which was causing me severe sciatica and is still sore today...not sure if it is related
