Amyloidosis
Amyloidosis, a rare disease caused by the accumulation of abnormal proteins called amyloids in organs that interferes with normal body functions. This protein does not exist in the body, but it can be caused by other proteins. Amyloidosis is a possible cause of trigger fingers. This can occur due to amyloid deposits in the tendon sheath, which can restrict the movement of the fingers and lead to trigger finger.
