He mentioned it to his doctor, who thought it was radial nerve pain.
Looking up symptoms and causes, this seemed likely. He has also had some trouble with his elbow on the same side now and then. He had used some stretching exercises for the pain in his elbow that had helped, He used the same ones again, and it has now helped with the pain in his head, neck and shoulder.
There are lots of videos with exercises for radial nerve pain, but I just printed out this sheet of exercises for him. a00791_therapeutic-exercise-program-for-radial-tunnel-syndrome_final.pdf (aaos.org)
When I was having ulnar nerve pain I also looked up and used stretching exercises with great success.
I am definitely a fan of exercises for pain relief! Non-invasive, no medications, and free! (Though, when necessary, I have been happy to pay a good physical therapist as well.)
