Well the return of numbness (paresthesia) reported today is not a good sign.
It certainly is not Raynaud's, and is likely to be a nerve impingement/entrapment. There is no reports other than all his fingertips being numb. However, it could be only 2 fingers are numb, unless you are thinking specifically about it, sometime people just generalize their statements to all.
Here is the sensory innervation (courtesy of wikipedia)
Some of the more likely causes:
Ulnar nerve entrapment - note the ulnar nerve is the one that you feel when you hit your "funny bone". With his prior elbow issues, this could come and go with swelling in the elbow.
Thoracic outlet syndrome
Cervical radiculopathy (pinched nerve)
Carpal tunnel syndrome
Obviously this is very concerning. With tests including MRI getting done today, we should have an answer soon.
