Benign Fasciculation Syndrome (BFS) is a fancy term that refers to neurological twitching that apparently isn’t harmful and has no apparent cause. I run a group on Facebook called “Benign Fasciculation Syndrome – Holistic Approaches.” We are always trying to figure out why we are twitching! Many of the people in this group have reported symptoms of Mast Cell Activation Syndrome (MCAS), which is basically the body overproducing mast cells, which kind of serves to be an ongoing allergic reaction of sorts. An autoimmune disorder is when the body is attacking itself, confusing body cells and tissues as a foreign invader. These two syndromes may be related.
Do you have a random twitch or two that won’t stop or moves around? You may have “Benign Fasciculation Syndrome” (BFS) or its sibling, “Benign Cramp Fasciculation Syndrome” (BCFS). BFS is not fatal – thus, the term “benign,” but it can be disruptive and distressing. It varies in symptomology, duration, and intensity. For some, it might just manifest as a slight twitch in the thumb. For others (such as myself), it can involve full body tremors and internal shaking. Benign Cramp Fasciculation Syndrome can also involve muscle cramping.
