From your description, your symptoms sound more like a viral or bacterial upper respiratory infection rather than TB or pneumonia, especially since there has been no persistent fever, weight loss, or severe breathlessness. Mild night sweats can occur during infections as your body fights it, and they do not always indicate TB.
Next Steps
Right now, continue rest, fluids, steam inhalation, and saline nasal washes. If you develop high fever, worsening cough, chest pain, breathing difficulty, or persistent night sweats for weeks, then further evaluation may be required.
Health Tips
For now, it does not look like TB or pneumonia.
