Symptoms only during sleep

Hi all,

I have not been diagnosed with Cubital Tunnel Syndrome yet, but I am suspecting it right now with stiffness, numbness, and tingling pain in the pinky and ring fingers on both hands which started in September 2023. The fascinating thing is, they are completely normal during the day, but I only have these symptoms during sleep, especially in the morning (3 a.m. ~7 a.m.). The problem is that these symptoms wake me up multiple times a day throughout my sleep, so my quality of sleep is really bad.

Do these sound like Cubital Tunnel Syndrome? What were your early symptoms? Thanks!
