A examine of greater than 60,000 individuals who examined optimistic for COVID and reported their signs discovered {that a} small proportion skilled ringing of their ears, sore eyes, rashes, pink welts on their faces or lips, hair loss and strange joint pains. A bigger evaluation of greater than 600,000 folks in Britain confirmed {that a} fraction of these with COVID additionally developed purple sores and blisters on their ft and numbness throughout their our bodies, amongst different maladies.
Docs aren’t certain why just some folks develop these uncommon signs. Genetics may play a task, Mulligan stated; vaccination standing might even have one thing to do with it, as an unvaccinated individual may need a extra extreme an infection, which might generate a distinct course of signs. Scientists have additionally discovered that the coronavirus can enter the bloodstream in a minority of individuals, he stated, which implies that it’s potential that the virus might enter varied organs throughout the physique and trigger signs past the respiratory system.

And there aren’t set guidelines for the way docs deal with them, stated Gebo. “We’ve definitive tips on learn how to deal with shortness of breath,” she stated, “however we don’t have definitive tips on these.”
Right here’s what else we all know in regards to the causes of — and potential remedies for — a few of these signs.
Bushy Tongue
Wholesome tongue cells quickly substitute themselves, Chin-Hong stated, but when older cells linger and construct on high of each other, it varieties a darkish, thick, fuzzy overgrowth, typically known as furry tongue. Even earlier than COVID, docs noticed sufferers with furry tongue associated to viral infections, smoking, antibiotic use and poor hygiene, he stated, including, “It’s extra widespread than folks suppose.”
“I do know it appears actually scary to folks,” he stated, however the affliction is usually non permanent. Some folks might also really feel a burning sensation inside their mouths. These with this symptom shouldn’t be “freaked out,” Chin-Hong stated. Individuals with furry tongue can use a tongue scraper or toothbrush to scratch away these tongue cells, they usually can be certain that to follow good oral hygiene to stop extra buildup.

For many individuals, that tingling sensation goes away in a matter of days, Gebo stated. If sufferers are in ache, she added, they need to seek the advice of their docs, who might suggest taking Tylenol or Motrin.
Individuals with persistent nerve ache, even after they get well from the virus, ought to seek the advice of their docs, stated Dr. Marc Sala, co-director of the Northwestern Medication Complete COVID-19 Middle.
Rashes
It’s well-established that viruses can induce rashes, Sala stated, and he famous that he has seen all kinds of pores and skin afflictions in sufferers with COVID.

Like most uncommon COVID signs, as unnerving because it is likely to be, the swelling usually resolves by itself — for causes docs aren’t completely certain of.
“We’re nonetheless studying about COVID,” Mulligan stated. “We don’t perceive the whole lot.”
