Calling it "a cautionary tale," on Tuesday, CNN's Alisyn Camerota spoke with Abby Gresko Barclay, a COVID-19 sufferer who has been dealing with various coronavirus symptoms for nine months. She is what's known as a "long-hauler," someone whose body has technically cleared the virus but continues to experience physical effects. When Barclay first began to experience symptoms last March, she had a hard time getting tested for COVID-19 because she didn't have a fever. (Now, doctors know that COVID is often, but not always, accompanied by fever). Since then, "It's been all over the place," she said. "It's impacted my entire body." Here's what Barclay said her initial symptoms were, some of which she continues to experience today. Read on, and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had Coronavirus.


Gastrointestinal Issues

Barclay said she experienced severe stomach cramping and diarrhea. Early in the pandemic, doctors didn't necessarily associate this with COVID. Now they know that COVID very often causes gastrointestinal symptoms—in some patients, it's the only coronavirus symptom they have. A review of studies published in November found that one in five COVID patients report GI issues of some kind.

Swollen lymph nodes are a common sign of infection, and because COVID-19 involves the respiratory system, it may cause swollen nodes in your neck. 


Sore Throat

This is one of the hallmark symptoms of COVID-19, according to the CDC. A European study of 1,420 coronavirus patients found that 53% of them reported having a sore throat.

Shortness of Breath

Shortness of breath is a common symptom of COVID-19, and it can linger for weeks after you've recovered from the illness. Take note: Serious trouble breathing could be a sign of ARDS (acute respiratory distress syndrome), which can be fatal. It requires immediate medical attention. Harvard Medical School advises that if you find yourself breathing harder or having trouble getting air each time you exert yourself, call your doctor.


Chest Pain

Chest pain, which can be frighteningly reminiscent of a heart attack, has been reported by many long-haulers. It may be caused by costochondritis, an inflammation of the cartilage that connects ribs to the breastbone—or it may be a heart issue. "Sometimes people get inflammation of the heart tissue itself and some chest pains. We've even had some people present with what they thought was a heart attack, and in fact, it was inflammation the heart tissue that was caused by the virus itself," says Dr. Stacey Rizza, a Mayo Clinic infectious disease specialist and researcher.


Muscle Aches

Muscles can become inflamed during any illness. COVID-19 causes inflammation throughout the body, and muscle pain has been frequently reported. About two-thirds of patients in the Long Hauler Symptom Survey reported long-term muscle pain or soreness.

According to the CDC, chills are a common COVID signifier. They're caused by the body trying to regulate its internal temperature and may follow or accompany a fever. According to the USC School of Medicine, chills without a fever can indicate your body is trying to fight off an infection.
