But five days later it had done something face lumps don't usually do.
A thirty-two years old Russian woman who experienced characteristically moving and itchy lumps on the face was diagnosed with a shocking condition.
The bump first appeared below her left eye, then reappeared on her upper left eyelid five days later.
Two weeks after she noticed the lump, the woman finally chose to have it checked. Then, it moved to her upper lip, which shows significant swelling in her photos. A brief physical examination revealed that the nodule was caused by a Dirofilaria repens, a parasitic nematode that usually likes carnivores like sea lions, cats, wolves, dogs or foxes. It had moved to just above her left eyelid - carrying with it an itching and burning sensation.
Specifically, the woman had a parasitic worm, whose movement she tracked in selfies. However, luckily, these worms can nearly never reproduce in humans, and all symptoms usually disappear quickly if the worm is removed - so if you've noticed any unusual lumps moving around your body after a mosquito bite, you should probably get to a doctor.

But history was not on Mexico's side because it had not won back-to-back matches at a World Cup since 2002. Hernandez added the second in the 66th, scoring his 50th goal for Mexico .
The report details how the woman from Russian Federation became the host of a parasitic worm after being bitten by a mosquito.
A case study featuring a lot of disturbing images about the woman and the worm in her face was published in the New England Journal of Medicine in a report titled "MigratingDirofilaria repens".
Doctors used a pair of forceps to surgically extract the lump, which turned out to be a long, white worm, the report said. He said that since 1997, there have been more than 4,000 human cases reported in these countries, particularly in Russian Federation and Ukraine. Vladimir Kartashev, a professor of medicine at Rostov State Medical University who treated the Russian woman wrote a study on dirofilariasis in 2015 which revealed that between June 1997 and June 2013 almost 1,300, mostly women who visited rural areas, were infected in Russia.
They increased from eight in 1997 to almost 200 cases in 2012.
What a woman thought was a lump on her face that mysteriously moved around from one part of her face to the other and occasionally itched, turned out to be something right out of a nightmare.
The worm rarely poses any dangers and patients make a full recovery once it has been removed.
