experiencing pain via touch on lower half of my left arm from elbow to bottom two fingers

Question

started out about 4 days ago with my left arm being numb from my elbow to my ring and pinky finger. I remember waking up in the middle of the night in excruciating pain for my entire left arm. Woke up and it was numb and uncomfortable. I dismissed it as having slept on my arm wrong or something. Had no strength in my grip either. It has progressively gotten better over the last 3 days, my strength is starting to come back... however, I am still experiencing pain to touching the skin on the lower half of my left arm and it still extends from my elbow into my ring and pinky fingers. if I squeeze my fingers I feel discomfort all the way to the bone. I looked it up yesterday a little and I thought maybe Cubital Tunnel Syndrome, but I'm not sure anymore from some of the answers of questions on here.
