Itching of finger joints

Kind of like an allergy. Have you ever been tested for allergens by a doctor? May be allergic to things that come into contact with in life, such as soap, washing powder, iron or other things, which may cause allergies. Go to the hospital to check allergens, determine what you are allergic to, and try to reduce contact with those things in your life.

If it doesn't itch, you can go to the drugstore and buy a tube of beryllium pharmacist (the word may not be these three words, but the name of the medicine is like this: skin pharmacist) to try.
