And, most importantly, check your temperature. Checking your temperature will also determine whether or not you can stay home, and feel better, or if it requires a doctor visit. Allergies do not cause high temperatures, as you're usually dealing with the discomfort of sinus issues, watery eyes, itchy skin, sometimes a cough, which can be remedied with over the counter allergy medicine/by taking local honey. A cold is usually indicative, and different from allergies, when your sinuses are clogged, or inflamed, you have a lump or scratchy throat, chills, feverish, disorientation, you have a persistent cough, etc... you can tell the difference between allergies and a cold. A cold usually causes a change in temperature, any temperature above 100.4 F. Also, COVID symptoms are indicative of a fever greater than 99.9F, accompanied by chills and lethargy. A sudden shortness of breath, or difficulty breathing, and lack of smell. It is still possible to contract COVID, even with immunizations. Keep in mind that studies have shown that COVID is airborne, just like influenza, and allergies. This is what all three (3) have in common, but the only difference is that you can contract influenza by touching infected surfaces. So, wash your hands often!
All in all, and basically...check your temperature! Always have either a digital thermometer, or a mercury thermometer on hand. If your temperature is above the norm/above 100.4 F, take aspirin, use a cold washcloth on the forehead, or take an ice bath, to lower your body's temperature. If your temperature does not go below 100.4 F, you must see a doctor right away. If you experience, shortness of breath, with a high temperature and chills, any yellowish-greenish-brownish phlegm, go to the doctor right away.
