The Common Cold: Timeline of Symptoms

Mar 16, 2022
You know that feeling you get every year and in late fall or early winter you start to get a sore throat, cough or runny nose and you start to wonder if this is just a

cold

that I'm going to get over in a few days or is it something else? I laughed. I need to see the doctor today. I'd like to talk to you about what causes the

common

cold

and how you can accurately identify the

symptoms

of a cold and know exactly what to look for. We will also talk about how. the flu or influenza infection is often different from

common

colds. hi, i'm dr.
the common cold timeline of symptoms
Maria Conley The

symptoms

that occur in a common cold or upper respiratory infection are predictable and often occur in a sequence. You don't need to see a doctor for the common cold, especially if your body is reacting in a similar way to the one I'll describe below if you start to experience more severe symptoms, such as a fever, or if it lasts for more than a day or two. You may need to see a medical provider, so what do you need to know about the common cold? First, most colds are not caused by the flu or influenza virus. for ten to fifteen percent of colds, influenza viruses only caused 5 to 15 percent of upper respiratory infections, second, the

timeline

of a typical cold goes like this, first, breathe the virus through polluted air or touching a contaminated surface, the virus is transferred from the hands to the mouth or nose, second, the virus infects the upper respiratory tract, third, the immune system reacts by activating macrophages, which are white blood cells specialized in fighting diseases.

These macrophages trigger the release of small proteins called cytokines. other proteins are also released, such as bradykinin, bradykinin is an important trigger of early cold symptoms such as sore throat and nasal congestion, cytokines, such as interleukin 1 il-1 and interleukin 6 il-6, cause fever and chills in some people and then symptoms begin. first a sore throat a sore throat is often the first symptom the pain you feel is due to the action of hormones prostaglandins and bradykinin on sensory nerve endings in the upper respiratory tract pain signals are transmitted to the brain through the cranial nerves in the area and then you can develop some swelling when you sneeze and the nose triggers the trigeminal nerve to trigger the sneeze C they enter the brainstem the brain triggers the Sinise reflex and then you can have a runny nose the trigeminal nerve also stimulates the glands to release a clear nasal discharge as the cold develops over the days the color of the nasal discharge may turn yellow and then sometimes green the color changes due to the presence of a increasing number of disease-fighting white blood cells in the fluid the color actually comes from a plain green protein mada Milo peroxidase which is contained in some of these cells the color of the nasal discharge just indicates how much inflammation is going on in your body this same rule applies to sputum you may be coughing up the same infection and then you may develop some pain in the sinuses map The sinuses that are on both sides of the nose often become inflamed and painful after nasal congestion begins increased pressure in the bony spaces of the sinuses and in the blood vessels near the sinuses can also get stuffy sinus pain often gets worse when you lie down due to pressure changes in the surrounding blood vessels and then you may develop watery eyes you actually have a small tunnel leading from your nasal cavity and opening into the inner corner of each eye this is known as the nasal lacrimal duct well this duct can become blocked due to swelling and congeal sction on the lining of the nasal cavity this causes tears to pool in the eyes and develop watery eyes then comes COFF which can last for over three weeks nasal irritation can cause sneezing but once the inflammation goes down through the larynx and approaches the lungs, a cough reflex is triggered.

Inflammation of the lining of the lower airways can stimulate the vagus nerve, which then transmits a signal to the cost center in the brain stem when the muscles contract when coughing. coffee flow becomes hyperactive when you have a cold when there is a lot of inflammation in the lower respiratory tract it can also COFFER yellow or green sputum unfortunately a cough can sometimes last several weeks after the other symptoms resolve and up to 50% of adults with a cold may also have muscle aches the inflammatory cytokines we mentioned can also cause skeletal muscle breakdown and can trigger the release of a hormone called prostaglandin e2 this hormone activates peripheral pain receptors leading to muscle pain.

Next, you may have a fever, although fever and adults with a common cold do not occur as often. You are more likely to have a fever if you are infected with the influenza virus or a virus the body has never seen before. This explains why babies are more likely to have a fever with any infection than adults. The common cold usually caused by the Rhino virus is not usually associated with a fever, although it can be when infected. Cytokines send signals to the hypothalamus. which is a temperature control system in your brain your body temperature rises and you may start to shiver this explains why you may get a fever r and chills with an infection at this time there is no cure for the common cold which may be caused to one of several different viruses that unfortunately mutate frequently although the effectiveness of the flu vaccine changes every year, it generally decreases the chance of becoming infected with the flu or influenza virus, which can cause severe symptoms.
I definitely recommend getting a flu shot every year. Unfortunately, there is no vaccine yet for the Rhino virus or the corona virus, which means there is no vaccine that will prevent you from getting the common cold. This also means that you can still catch a cold easily after getting the flu shot, but your chances of getting an influenza infection will likely be lower; however, if your symptoms are similar to the ones I mentioned above, there is a good chance that you just have a rhinovirus or coronavirus. infection that will get better over time without any specific treatment, sometimes you just have to wait for your own immune system m to fight the infection which normally takes seven to ten days
