PENNY EDIBLE HERBAL MEDICINE PENNINGTON, N.Y. (AP) While many people think their sore eyes are a sign of something serious, a new study suggests a more mundane source of irritation could be an ear infection.

Researchers at Penn Medicine found the soreness can be caused by bacteria, viruses, parasites or other life forms.

They also found it can be linked to allergies and other health conditions.

“The study suggests that the ear infection or other condition that causes sore eyes is one of many possible sources of irritation,” said Dr. Michael Hetzel, the study’s senior author and an associate professor in Penn Medicine’s department of otolaryngology and ear, nose and throat.

“It’s a bit like a migraine, you can feel a pain but it’s just that the pain doesn’t go away.

It’s a feeling of the pain is not necessarily a problem.”

Hetzel and his colleagues analyzed data from more than 6,000 people with severe, chronic ear infections in the U.S. and Canada.

The researchers compared the patients’ ear infections to the symptoms of allergies, inflammation, ear infections and ear infections with a common cold.

“Our findings indicate that ear infections can trigger ear infections, and that these infections can lead to a variety of adverse health outcomes, including ear infection and ear infection-related pain,” the study says.

The authors said the study is the first to document that ear infection causes ear infections-related discomfort and pain, and suggests the ear infections could be another factor contributing to other ear infections that cause irritation.

“This is a case where we found a very different type of inflammation associated with ear infections,” Hetel said.

The study, which appeared in the journal PLOS One, looked at data from about 5,600 people with acute ear infections.

The participants had symptoms of ear infections ranging from mild to severe.

The most common ear infection, the ear wound with the most irritation, was the earworm, a common tick that has been blamed for millions of ear injuries each year.

The researchers used a software tool called PLOTS to look at the relationship between the earworms and the ear, the skin, the head and other symptoms of sore eyes.

The findings show ear infections are associated with inflammation, which is associated with the symptoms in sore eyes, the authors write.

“So, in terms of the inflammation that is associated, it’s related to ear infections — that is, the inflammation is associated — but we see that the inflammation also can be associated with other conditions that could also trigger the ear injury, such as allergies and inflammation,” Hettzel said.

Ear infections with inflammation can cause inflammation of the ear tissue that forms the bridge of the nose and the underlying ear, which can result in inflammation of other parts of the body.

The ear infection caused the most soreness, the researchers report.

Ear infections with inflammatory ear infections were associated with chronic ear infection in about 30 percent of the participants, the research showed.

In addition, inflammation of different types of tissues of the head, neck and neck area, including the scalp and other facial and head tissues, was also found to be associated, but it was associated with fewer sore eyes than the ear worms.

The results suggest inflammation is a risk factor for sore ears, but the researchers say it’s important to understand that ear inflammation is not a disease-specific condition.

“What this suggests is that there are other conditions and other people that could cause sore ears,” Hetzel said, adding that it could be that the sore eyes and sore muscles are more common in people with a chronic ear condition than those without.

Hetel and his team say it would be wise for people to avoid using products made with earwax and other products that are made with other materials such as petroleum jelly.

Hettel said they would recommend avoiding earwaxy ear products, which include ear waxes and polyester products, as well as those made with petroleum jelly or other oils.
