Long COVID Symptoms Linked to Effects on Vagus Nerve
In a small study of 22 people with long hauler post-COVID, 27% of participants showed evidence of inflammation of the vagal nerve. This nerve tends to counterbalance adrenaline and supports digestion in our body's dance of autonomic function. It shows one more mechanism, in addition to limbic and hypothalamic dysfunction, contributing to the sense of adrenaline overdrive and POTS that many people with CFS and fibromyalgia have. The decreased movement of the diaphragm muscle that separates the lungs from the abdomen may also be one factor contributing to the sense of breathlessness that many people have.
Meanwhile, another study showed that famotidine (Pepcid) stimulates vagal function to block cytokine storm. This is just one more reason why Pepcid during COVID can be so lifesaving. It may also help with the vagal nerve dysfunction and chronic viral infections seen in CFS and fibromyalgia.
