Postviral vagal neuropathy (meaning a damaged vagus nerve) is found in some #LongCovid patients.

This can result in things like vocal cord dysfunction & can be the reason some patients have persistent shortness of breath but normal imaging:

The vagus nerve is a super important nerve (and is also the longest cranial nerve, running from the brainstem to the colon). Damage to it can impact many parts of the body (I find the decreased production of stomach acid interesting here) 2/

It can also cause a condition called gastroparesis, which may explain some #LongCovid symptoms 3/

It also has significant sensory and motor functions, including in the role of taste and in heart rate.

Damage to the vagus nerve should be a key area of investigation in #LongCovid research. 4/
