Colds and fevers often occur due to viral infections, especially when symptoms such as body aches, a runny nose, a sore throat, or tiredness appear suddenly. Most mild viral infections get better in a few days with rest, drinking plenty of fluids, and treating symptoms as needed. The best medicine depends on which symptoms are bothering you most, such as fever, blocked nose, sneezing, body pain, or cough. Doctors usually recommend paracetamol for fever and body pain, as it is safe when taken at the right dose. Antihistamines or combination cold tablets can help with sneezing, a runny nose, and nasal irritation, but some may cause mild drowsiness or dryness. Drinking warm fluids, using steam inhalation, getting enough sleep, and eating light meals can also help you recover and feel less weak. Antibiotics are not usually needed for a simple viral cold, and taking them unnecessarily can cause side effects or lead to antibiotic resistance. If you have a high fever that lasts several days, trouble breathing, chest pain, confusion, or feel much weaker, you should consult a doctor, as these could be signs of a more serious infection.
