Hi @jeanmnyc
Based on my experience with CTS & DeQuervain's Tenosynovitis and my orthopedic surgeon the exact cause of De Quervain’s tenosynovitis is unknown, but is usually seen in individuals with repetitive hand or wrist movements, injury to the wrist or tendon, and inflammatory conditions such as rheumatoid arthritis and inflammatory arthritis. De Quervain’s tenosynovitis is most common in pregnant and middle age women.

DeQuervain's and carpal tunnel syndrome both pertain to inflammation of the tendons involving the thumb, but carpal tunnel syndrome involves more. It involves nerve damage. CTS involves the median nerve which is the most vulnerable component.

Diabetic Neuropathy can also share many characteristics. Approximately 60 to 70 percent of people with diabetes will eventually develop form of neuropathy, or nerve damage, according to the National Institute of Diabetes and Digestive and Kidney Diseases. This nerve damage can happen anywhere, but tends to affect the extremities (hands and feet) first.

I’m curious what does your physician suggest??

Curious,
Dawn
