Based on your symptoms, you are likely experiencing a viral cold or seasonal allergies. For relief, you can take an over-the-counter antihistamine (such as Diphenhydramine or Cetirizine) before bed to help with watery eyes, a runny nose, and to aid sleep. For throat pain and general malaise, a pain reliever like Acetaminophen or Ibuprofen is recommended. You can also use a saline nasal spray or a decongestant spray (for no more than 3 days) to clear your blocked nose. Please stay hydrated, rest, and consult a doctor in person if your symptoms worsen or if a high fever develops.
