Carpal tunnel syndrome, or median neuropathy at the wrist, is a condition where the median nerve is compressed at the wrist. This leads to paresthesias (pins & needles) and muscle weakness in the hand. Night symptoms and getting woken up is also something that from your subjective assessment would be ringing bells to test for carpel tunnel syndrome. But what are these "tests" you speak of??
The median nerve sits between flexor digitorum profundus and flexor digitorum superficialis
This position reduces the size of the carpal tunnel, so if you did
have it, the symptoms would be aggravated temporarily. A +ve
test would reproduce pain, numbness or tingling.
Uses a tapping movements over the line of the median
nerve over the flexor retinaculum area.
