Since your cough improves with antihistamines, your symptoms are likely due to environmental allergies or post-nasal drip. To treat this effectively, continue taking a daily non-drowsy antihistamine (like Cetirizine or Loratadine) and consider adding a fluticasone nasal spray to reduce nasal inflammation. Using saline nasal rinses can also help clear allergens. Since you have no fever, a bacterial infection is unlikely. Please stay well-hydrated. If your symptoms do not improve within another week, worsen, or if you develop a fever or breathing difficulties, please consult a doctor for a physical examination and targeted prescription.

Shivering with a high fever and body aches is usually due to an active infection. Keep yourself well hydrated by drinking frequent fluids, take light meals to help your body cope better, and rest as much as possible to support recovery. You can use simple measures, like a lukewarm sponge, to feel more comfortable during a fever and to keep your body warm during shivering episodes. Avoid self-medicating beyond basic care, as the cause is still unclear. Try to keep track of your temperature and how often the fever returns. If the fever remains high, worsens, or you feel very weak, it needs attention. Consult a doctor promptly for proper evaluation and treatment.

If typhoid does not improve after a few days of treatment, it usually means the infection needs closer monitoring or a change in treatment. Keep yourself well hydrated with plenty of fluids, such as water or oral rehydration solutions, and take soft, easy-to-digest foods such as khichdi, soup, or boiled vegetables so your body is not strained. Take complete rest and avoid heavy activity so your body can recover, and follow your medicine schedule strictly without missing doses. Maintain good hygiene to prevent further infection and support healing. If the fever stays high, weakness increases, or you feel worse, inform your doctor to review your treatment and ensure proper recovery.

Frequent fever, cold, and tonsil issues often happen when immunity is low or when you are repeatedly exposed to infections. Try to build a steady routine with regular sleep, balanced meals rich in fruits and vegetables, and enough fluids to support your body?s defence, and maintain good hygiene, such as handwashing and avoiding close contact with sick people. Warm fluids and simple home care can help soothe the throat, and gentle exercise can improve overall resistance. Avoid very cold foods and sudden exposure to cold weather, as they can trigger symptoms. If episodes are very frequent or severe, they need attention. Consult a doctor to determine the cause and guide you on ways to strengthen your immunity.
