Take the medicine until all liquid or pills are gone. Even though you will feel better in a few days, continue to take the antibiotic all 10 days to keep the strep throat from flaring up. Since swollen tonsils can make some foods hard to swallow, a soft diet for a few days may help. You may have headache, fever, chills, aching muscles all over, lack of apetite, sore throat, nasal discharge, dry cough, weakness, and pain or burning in your eyes. That's the flu.
Flu is caused by a virus.
It usually goes away by itself. Sometimes, complications develop such as bronchitis, sinus or ear infectios, or pneumonia. Complications are serious for the elderly and for people who have chronic disease like diabetes and heart disease. Bed rest is very important. Alcohol, damp washcloth on your forhead may relieve the feverish feeling.
