If you're still experiencing CTS symptoms after conservative treatment, you may have an underlying condition or risk factor that has not been inadequately addressed. Risk factors for recurrent CTS include:
• diabetes
• obesity
• hypothyroidism
• vitamin deficiency
• inflammatory arthritis
• excessive alcohol use
After surgery, recurrent CTS may develop if the surgery fails to treat the median nerve affected by carpal tunnel. Aside from chronic CTS, recurring symptoms may also be attributed to problems associated with scar tissue development after surgery.
