You would need a doctor to examine your fingers, hands and wrists to make a formal CTS diagnosis. Symptoms usually come on gradually and may include:
pain
numbness and loss of feeling
tingling
swelling
stinging
weakness and difficulty gripping
clumsiness
inability to distinguish hot from cold by touch
CTS is more serious than a temporary sprain. It occurs when your median nerve - which extends from your forearm to palm - gets compressed at the wrist by inflamed tendons and ligaments.
