Go get ALS ruled out. You can’t go on like this. Let them do a nerve conduction test or something. Don’t do anything like a spinal tap! Nothing so invasive with such risks. Not now, not unless there is all sorts of other data pointing towards needing one.
I have a bunch of ALS symptoms too! But it’s been over ten years of it and vitamin D makes a huge difference in relieving the symptoms. ALS gets really bad fast. Within three years of diagnosis people usually are becoming severely disabled. I don’t have twitching, but I have terrible muscle fatigue and cramping in all my body. I used to shake after using a muscle group repetitively, I literally could not hold a glass for fear of dropping it my hand would get so weak and shaky. Probably, if I went to enough doctors one would have diagnosed me with ALS, one diagnosed me with fibromyalgia, which still makes no sense to me. Luckily, my endocrinologist diagnosed me with severe vitamin D deficiency, or I think I would have become crippled.
Typically, ALS doesn’t begin until after age 40, but there are rare cases of younger people. Most people start becoming clutzy, practically tripping over themselves, falling down, dropping things, difficulty speaking, just twitching doesn’t add up to ALS. Plus, you said your dad has twitches, so the most likely explanation is a genetic tendency for twitching.
Twitching in your body at night, do you mean a few jerks at night as you begin to fall into slumber land? That’s common and normal. Is that just starting now, you’ve never experienced that before?
Did you do anything differently those two days? Less caffeine? You were worrying less? When the twitching started back up did you have more caffeine than usual? Something made you very anxious again?
