A team of scientists is proposing a new explanation for some cases of long Covid, based on their findings that serotonin levels were lower in people with long Covid. They said that the biological pathway that their research outlines could unite many of the major theories of what causes long Covid: lingering remnants of the virus, inflammation, increased blood clotting and dysfunction of the autonomic nervous system.
That sounds scary. I take a TCA and SNRI daily and sometimes I also need to take sumatriptan. Fear of serotonin syndrome is always at the back of my mind.
