I have been having body wide muscle twitching, is it ALS Amyotrophic Lateral Sclerosis?

I have been having body wide muscle twitching for 4 or 5 days now. Pain in my neck when I turn a certain way. Crackling in my jaw and right leg when I move it. Very fatigued. Headaches. Could this be ALS? I’m so scared and can’t see anything else it could be. I haven’t drank coffee in 3 days to see if that could be it. I also have ringing in my ears at time and some pain in my back. I feel really weak as well.

Age: 28
Medications: Celexa, flexiril, naproxen
General Information: I had a blood test to see if my electrolytes were off and haven’t gotten the results back.
