A completely blocked nose that does not improve despite medicines is often due to severe nasal swelling or sinus blockage rather than simple congestion. Do frequent steam inhalation, stay well hydrated, keep your head slightly raised, and avoid dust or cold exposure to help open the nose. Limit the overuse of nasal sprays like Otrivin, keep the nose moist, and try gentle saline rinsing if comfortable. If the blockage persists or you develop facial pain or headache, consult a doctor to review your treatment and properly clear the sinus cause.

A viral infection usually causes a cold, headache, and fever. Take proper rest, drink warm fluids, do steam inhalation, and eat light food to help recovery. Keep yourself warm, stay hydrated, and monitor your temperature and symptoms. If fever is high, lasts more than a few days, or symptoms worsen, consult a doctor for proper evaluation and care.

Knee pain after a recent fever is often due to post viral inflammation affecting the joints. Rest the knee, avoid strain, use a warm compress, stay hydrated, and do gentle movements to reduce stiffness. Eat nutritious food and allow your body time to recover before returning to heavy activity. If pain persists, worsens, or swelling or difficulty walking occur, consult a doctor to determine the cause and guide appropriate care.

A sudden fever is usually due to a viral infection and may settle with simple care. Take proper rest, drink plenty of fluids, keep yourself lightly covered, and monitor your temperature for changes. If already advised earlier, you can take a simple fever tablet, but avoid taking multiple medicines on your own. If the fever rises, persists, or you develop other symptoms like severe pain or weakness, consult a doctor for proper guidance.

Cough, cold, and fever with vomiting are usually due to a viral infection affecting both the body and the stomach. Take proper rest, drink small, frequent amounts of fluid, do steam inhalation, eat light foods, and avoid oily or heavy meals to help with recovery. Stay hydrated, monitor your fever, and avoid taking multiple medicines on your own. If vomiting continues, you cannot keep fluids down, or symptoms worsen, consult a doctor for proper care.
