@keithl56 Hi there! Did you get your EMG result and what is the result? I hope you feel better. I've started all over body muscle twitching since 2.5 weeks ago today (October 6th, 2025). It started with lower eyelid for 6 days daily, then it moved to other parts of body, all over, randomly, on and off, only happens at rest (when I don't tense my muscles), and sometimes I get muscle tension too due to the anxiety anticipating the twitches. I've been checked by a PCP who said nothing wrong with me, but told me to return to her in 2 weeks if my muscle twitching still occurs so that she can refer me to Neurologist for more tests and blood work. I hate this condition! This is all too new for me!

The odds are that there is nothing major wrong. Before trying to get a neurology appt (that is likely to take a while!) I would ask the PCP to order the bloodwork. There are several conditions that can cause the fasciculations that are not neurologic in origin. Various deficiencies and even Lyme disease can cause your symptoms, and these can be diagnosed with a simple blood test. You might be able to avoid the neurologist and the resultant EMG's.

The important thing is to find out (if possible) what is causing this so that you can have peace of mind. Otherwise, the anxiety can just exacerbate your situation and make it worse as it did with me.

I still have my fasciculations but knowing that it is innocuous BFS allows me to not perseverate over them. Good Luck!
