These are my findings:

__Symptom no 1. Lumbar vertebrae__
Question 1: It came abruptly (so repair phase)
Question 2: defined place
Question 3: the pain gets stronger when I move (so it's a symptom of the stress phase)
Question 4: Yes I had the symptom before, in my teens and my twenties.
Question 5: I don't remember what happened before it appeared, but I remember that I used to have that same issue before in my cervical vertebrae but only temporarily. Now it's a consistent pain in my lumbar vertebrae. That is new.
Question no 6: No symptoms appear together.

Wiki says: Lumbar: Central personality, ego weakness, unable to withstand pressure, no "backbone", no support.
Well, I guess I need more backbone to withstand pressure. That's already interesting, but unfortunately there hasn't been the "click"-moment yet. Any further ideas?

__Symptom no 2: Finger joint__

Question 1: It came abruptly (so repair phase)
Question 2: defined place: it's the left hand (and Im right handed so: It's the side of mother, inner child, no kids, no pets)
Question 3: the pain gets stronger when I move the finger. Also the joint has become thicker and I have a restriction of bending it. (So active and recurrent stress phase. But doesn't this contradict question no 1 where I detected that it has to be a repair phase since it came abruptly?)
Question 4: I never had this symptom before
Question 5: I don't remember what happened before it appeared. But I remember that I was working a lot with that finger that day on the computer. 
Question no 6: No symptoms appear together.

Wiki says: Finger has to do with skill megalomania. And regarding joints and therefore cartilage Wiki states: I'm too soft!
I can not stand it!
I should have solved that more elegantly!

META meaning:
I am strong and flexible like a tree!
I love moving in the world, feeling it and letting go.
Life is like a dance!

Unfortunately there hasn't been the "click"-moment yet either. 
So, I'm grateful for any suggestions!
