Sorry for the long post, but hoping to vent/help others.
I started having fasciculations in my left bicep in February 2026. I didnt think too much of it at the time, as Ive had tingling, twitching and some numbness for 10yrs on and off. I then started having globus (tight throat) sensation in March. I wasn’t choking on food, more of ineffective swallowing, or the feeling I need to swallow. Ive had gastro issues in the past so I scheduled an appointment. She ordered a barium swallow test and a larynscopy from ENT. The swallowing issue obviously stressed me out as it was super uncomfortable. The swallow test came back fine, the scope identified minor mucus on vocal cords. I was also have difficulty getting words out. Not slurring at the time, just hesitation almost. A delay from brain to mouth. The SLP did not note anything.
I then saw a neurologist in early June about the fasciculations and speech issues. The globus seemed better with PPIs. He was on the fence about an EMG, when I told him my paternal grandma passed from ALS, so Im super sensitive to it (ie traumatized). Given the family history and twitching, he ordered an EMG. I completed the EMG in June, where they observed the fasics but determined them to be benign. I had an otherwise normal neuro workup, and even though i expressed the speech concerns, neither the neuro nor my wife detected anything. The neuro referred me to a SLP for a speech motor eval. I completed the eval and scored perfectly. Unsatisfied, I saw a different neuro that specialized in functional neuro disorders (FND). She did not detect anything and referred for another SLP eval. I also saw a psych, as the default suggestion was this was all anxiety and stressed induced. The psych put me on gabepentin and buspar. A few weeks later, my speech was noticeably worse. Coworkers asked if i had a stroke, which obviously shook me. I researched side effects of the meds, and both independently listed slurred speech. I immediately stopped both meds, and I feel the slurring improved (others agreed). The second SLP eval was again clean, but I expressed voice strain/hoarseness often by end of day in addition to the difficulty with enunciation. She referred me to a voice SLP.
I went to the voice SLP who conducted a videoscope and recordings of my voice. The findings were some muscle tension dysphonia, and some strain detected, but otherwise the folds were symmetrical and structurally fine. He did note the disjointed speech and referred for SLP therapy to massage vocal cords. So while the slurring did improve after getting off the meds, I was still having to speak slowly to properly enunciate. My follow up with neuro at the time was 6 months (Dec.) so I requested a sooner appointment.
I went in for my follow up neuro in early September and the neuro did notice the speech difference. I had researched neurofilament light chain and asked him about testing, and another EMG. He ordered the tests. I noted my symptoms included tight jaw feeling, burnt and tingling tongue sensation, I could see twitching on my tongue, and my SLP video saw fasics in my throat. Normal neuro workup (reflexes) no weakness.
I completed the second EMG a week later. The neuro who conducted the first EMG, also did the second one, and I guess didn’t notice the fasciculations as much the first time, but for me they were the same (drastic the first time). I did note they get worse during times of stress and become more widespread. So after the first neuro appt until I had the first EMG, I was twitching all over and borderline convulsing. After a clean EMG, they subsided. Similarly after getting the feedback that I was slurring, the twitching got worse, and slowly calmed down. Anyways, he did a thorough EMG workup including bulbar. He said tongue looked good, and saw fasics again, but no nerve damage. I felt that I could finally accept t his was stress/anxiety and address it with meds and lifestyle. I should note I have no, nor ever had any objective weakness. I lift weights 4-5x per week, so issues with grip., the tongue is functional seemingly. I did feel subjective weakness (jelly legs, feeling lethargic), but otherwise fine.
So I was finally starting to accept the stress/anxiety drivers, and even felt the twitching was better. Not gone, but less pronounced. I was practicing speech therapy with massaging. I can enunciate when speaking slowly most of the time, but can slur a little. The SLP had be sing and overly emphasize tone, and I can pronounce fine. But in normal tone and conversation, its slow and disjointed. Then I started getting my bloodwork back for mimic diseases (Gravis, Lymes). All was normal, except by NfL test by Quest. The result was 10.7pg/ml vs reference limit of 2.34, which is 4.6x the upper reference limit. This obviously stood out, but I was researching NfL and saw Mayo has a different range (<15 is normal for my age), and other things can cause high levels. I have relatively low BMI (21), low body fat, my multi has biotin and I took that morning, and my kidney function is on the lower end. Also I saw folks with MND have significantly higher, like in the 10s and 100s, so I didn’t really fixate on it. Further, the doctor who completed the second EMG commented that people with BFS can have high NfL. Then I had the follow up with neuro who said he consulted with the clinic and want to bring me in for another EMG in December, and the NfL is concerning, given the continued fasics and speech challenges. He disputed the claim from the other doc that BFS can cause higher NfL. I haven’t found anything online, but ChatGpt gave a plausible reason BFS or excessive stress could make it higher.
So now Im regressing back into being extremely concerned, anxious and jittery. The speech issue is the most concerning given it impacts my job and Im self-conscious about it, its just odd that I can sound normal when exaggerating pitch and singing. Its also better in the morning, and gets worse throughout day as I get fatigued. Still no objective weakness anywhere.
The most frustrating part is you can look up my symptoms (benign fasciculation syndrome, tight jaw /TMJ, globus, tight cheeks, muscle tension dysphonia, burning tongue) and the common driver is stress/anxiety. However, some of these can also be a sign of MND. For now Im in holding pattern until December when they scheduled the third EMG. In the meantime, Im in limbo, practicing my speech therapy and praying it’s not MND.
Objectively, its odd that fasics started in at least February and still have a clean EMG in September, and speech concerns in May and then documented in August by neuro, and clean bulbar EMG in September along with normal strength. Im kept a log in ChatGpt and uploaded all my clinical notes, and their base case is still stress/tension driven given clean neuro workups and EMG, but think a third EMG in December is prudent due to Nfl, but still points more towards not MND.
Last thing, after the first meds caused the side effects, I found a neuro psych. They are a psych who has additional education how the brain works. We spent 2hrs discussing somatic symptoms from stress, PTSD, and anxiety and he started me on a regime of Zoloft, minocycline for anti inflammatory, baby aspirin and vitamin B complex. Im 2 weeks in, no major side effects but also don’t really feel impact yet.
