1. Pain in the ear
A common complication of acute respiratory viral infections is otitis media — inflammation of the mucous membrane of the middle ear cavities and the tympanic membrane. It occurs when an infection travels through the auditory tube from the nose into the ear cavity. Symptoms of the disease are as follows: severe pain in the ear, which radiates to the head and teeth, temperature 38–39 ° C, hearing loss, tinnitus. Periodically, pus may come out of the ear, after which the pain subsides. The danger is that the acute form can become chronic, and this sometimes leads to hearing loss. Therefore, it is so important to start treatment right away — the doctor will prescribe antibiotics, ear and nose drops, painkillers and anti-inflammatory drugs. After recovery, be sure to check your hearing to rule out inflammation of the auditory nerve.
2. Pain in the eyes, tearing
Painful sensations in the eyes occur due to high temperature and intoxication. Influenza is characterized by a symptom of red eyes, when the whites turn bright red due to the expansion of numerous small blood vessels. With adenovirus infection, thin grayish films appear on the inner surface of the eyelids and in the corners of the eyes. Special treatment is usually not required. Another thing is if bacterial conjunctivitis occurs, the main symptom of which is stuck together eyelids in the morning. Then the doctor will prescribe rinsing and drops. The main rule for inflamed eyes is peace, therefore, during the illness, it is better to give up the TV, computer and books, and also avoid too bright lighting.

3. Bruises and nosebleeds
Most often this is due to the drying of the nasal mucosa in a room with dry air. In addition, exposure to viruses weakens the walls of blood vessels, making the capillaries fragile. They bleed easily when you blow your nose or sneeze.
If your nose bleeds a lot, in no case do not throw your head back! First of all, calm down. Sit with your head tilted slightly forward to keep blood from running down your throat. Press the nose just below the bridge of the nose with two fingers and place a cool object on the sides of the nose. After 10 minutes, loosen your fingers and if the bleeding has not stopped, do the whole procedure again. And if that doesn’t help, call an ambulance.
If you easily get bruises on your body, it makes sense from the very beginning of the disease to take vitamins C and P or ascorutin for prevention — these vitamins strengthen the walls of blood vessels.
4. Pain in the heart
Even if ARVI passes without fever, then after a week or two weakness, shortness of breath may appear — this is how post-viral myocarditis (inflammation of the myocardium) manifests itself. Be sure to see a cardiologist and do an ECG. In addition to the main treatment that your doctor will prescribe, you will definitely need a sparing regimen. In no case do not load the heart with physical and emotional stress, so that chronic pathology does not occur. Minor heart failure can go away on its own, it just takes the body some time to recuperate. It is very useful during this period to support the heart with herbal infusions of motherwort and hawthorn.

5. Drawing pains in the lower back
If the temperature jumped and at the same time back pain appeared, most likely an inflammatory process in the kidneys (pyelonephritis) began. But sometimes it is almost asymptomatic, but pay attention to how often you go to the toilet and how much fluid comes out. If you notice that the urge has become less frequent and there is less urine, there is cause for alarm. However, when the inflammatory process intensifies, it will be the other way around: more frequent urges, more urine.
Without a general urine test, it will not be possible to recognize pyelonephritis (in this case, an increased content of leukocytes will be found in it). And the treatment will be antibiotics, herbal uroseptics, herbal kidney teas. Also, the reason for an urgent visit to the doctor should be flakes (turbidity) in the urine, pain during urination.
6. Abdominal pain, intestinal upset
Sometimes, along with a sore throat and a runny nose, nausea and loose stools appear, less often vomiting. In such cases, doctors talk about viral diarrhea, which can be transmitted like a common cold — by airborne droplets. However, the main infection occurs as with ordinary food poisoning — through dirty hands and utensils. Help lies in the frequent replenishment of fluids. Cook compote from dried apricots, strain, add a teaspoon of salt, 1/2 teaspoon of soda and a tablespoon of sugar (per 1 liter). Drink in small sips throughout the day, alternating with plain water.
7. Aching pain in the bridge of the nose
Especially if it increases with tilting the head, sinusitis can be suspected. With this disease, there are also a number of symptoms: headache and toothache, nasal congestion, discharge from the nose with an unpleasant odor, the temperature rises to 37.5 ° C, pain is felt when pressure is applied to the cheeks and forehead. Usually the treatment is complex: antibiotics plus mucus thinners. In addition, it is important to regularly rinse the nose with a solution of sea salt and use vasoconstrictor drops. It is necessary to start treating acute sinusitis as soon as possible to prevent the infection from spreading beyond the sinuses, and with proper therapy it will pass in a week.

8. Cough, sweating and weakness
No wonder the inner surface of the respiratory tract is covered with epithelium, whose task is to detain all uninvited guests (bacteria and viruses). The body begins to fight from the very first hours, but if the infection drops below, it can cause tracheitis, bronchitis or even pneumonia. When, against the background of a small or already normal temperature, there was a sharp increase in it, chest pain, severe weakness, sweating appeared, and the cough became painful, urgently consult a doctor. Please note that with pneumonia, the temperature is not always high, but shortness of breath and weakness will be necessary. The doctor should listen to your lungs, may order additional tests and x‑rays. Of the drugs — anti-inflammatory, expectorant, antihistamines. Antibiotics for bronchitis are prescribed only at high temperatures and yellow-green (purulent) sputum, but with inflammation of the lungs, one cannot do without their loading doses.
