[Update] Thanks to the answer, I acknowledge now that I am heading towards "ulnar nerve entrapment" where one injury is Ulnar claw -- more common with males particularly training in gym with large weights and tennis players. This is due to stronger muscles blocking the ulnar nerve. The Wikipedia picture below at rest resembles the situation.
I have been under intensive training such as CFT, weight-lifting, tennis and climbing which all require a massive amount of effort on hands and fingers. On the morning I can feel that my fingers are not relaxed enough: particularly little finger and ring fingers which get an extra effort in dead-lifting, tennis volleys and tennis servings. This is a problem in tennis where non-relaxation can easily turn into pain due to fast swings.
