I have tightness and stiffness in my fingers and hands in the mornings?

AM stiffness. This is a common symptom in people who have arthritis of different kinds. Impossible to say what kind without an exam. For most people the stiffness works itself out after a little while. Hot showers or baths help. Gentle opening and closing of the fingers usually helps. Can be a nuisance but usually not much can be done about it.
