Based on your description, it sounds like you may be experiencing symptoms of a viral infection, such as bronchitis and sinusitis. To help alleviate your symptoms, you can try taking over-the-counter medications like Advil or Tylenol for muscle aches and headaches. A decongestant containing pseudoephedrine or phenylephrine may help with sinus and ear discomfort. You can also try a cough syrup containing dried ivy, like Helixia Prospan, to help with your cough. It's important to monitor your symptoms and if they persist or worsen, it may be necessary to see a doctor to rule out a bacterial infection. It's always best to consult a healthcare professional for personalized advice.
