Simmer down now. I am a lot like you... you know... except im a guy... but anyways. ALS is a disease of the motor neurons; not the sensory ones. In addition, widespread twitching as apposed to concentrated twitching points away from ALS. I too have ulnar nerve entrapment, and yes, I get the tingling, pain, etc. Try wrapping your elbow in a towel and taping it up so your arm is forced to stay straight at night. My orthopedist told me my CTS was due to sleeping w/ my arms bent underneath me. I too was in a panic like you, and truthfully am still somewhat apprehensive. That is why I am going to a neuro to get this settled once and for all, even though all my doctors say that anxiety is most likely the culprit, and nothing is indicative in my case of ALS at this time. Your case also sounds simliar to mine. Just relax. Take a breath. I had a breakdown 6 months after I started twitching; the anxiety was so bad and the twitches feed off anxiety as well as create more. It is like a viscous cycle. Nevertheless, go to a doctor. It will help put your mind at ease. Remember, ALS is rare and BFS is common. It is even rarer for ALS to present with twitching absent of weakness/atrophy if it does so at all. Most doctors say that twitching in the absence of objective weakness/atrophy is not indicative of ALS. It is also important to know that ulnar nerve entrapment (cubital tunnel syndrome) can infact cause atrophy and weakness in your hypothenar muscles as well as the muscle on the top of your hand between your thumb and index finger. Im sure your fine.
