Massage Therapy as a profession can be brutal on the joints of your fingers, thumbs and elbow. These joints usually suffer the most abuse. Excessive joint compression can be a factor but most often the cause of problems is simple: chronically over-used and over-tight arm muscles that pull on where their tendons attach at these joints, causing inflammation (tendinitis) and functional misalignment resulting in pain and dysfunction. When your arms and hands don’t work, you don’t work. When I worked as a sports massage therapist, my lack of a daily maintenance routine stunted my career and limited my effectiveness.
