  • symptoms are worst at night which may be relieved by
    • hanging the arm over the side of the bed, or by shaking the arm
    • flicking the wrist - known as the flick sign
  • decreased grip strength
  • motor wasting and weakness lead to thenar wasting and weakened abduction of the thumb – seen in severe, chronic carpal tunnel syndrome,
  • clumsiness or reduced manual dexterity e.g. – difficulty in carrying out fine tasks such as doing up buttons or become clumsy and drop items
  • trophic ulcers at the tips of thumb, index finger, or middle finger
