I was recently diagnosed with carpal tunnel syndrome. The doctor also mentioned tenosynovitis. What is this? Is it related to carpal tunnel syndrome?
"Teno" refers to tendon, and "synovitis" means swelling inside the lining around the tendon. Carpal tunnel syndrome (CTS) occurs when pressure is placed on the nerve as it passes through the wrist.
Anything that takes up space in the carpal tunnel can cause tendinitis and then tenosynovitis of the wrist tendons. Doctors used to think tendinitis/tenosynovitis caused CTS. Studies have since shown that tenosynovitis is more likely the result of CTS. In other words, the CTS develops and then causes tenosynovitis.
