Your chest and shoulder pain during sneezing is likely due to temporary muscle strain from coughing, which is reassuring since you have no breathing difficulties. To relieve a dry cough, you can use a cough suppressant like dextromethorphan, or an expectorant like guaifenesin for a wet cough. For the muscle pain, an over-the-counter anti-inflammatory like ibuprofen or a pain reliever like acetaminophen can help. Please rest and drink plenty of fluids. If you develop difficulty breathing, worsening chest pain, or a high fever, please consult a doctor in person for a proper evaluation.

A long-term cough that worsens with a cold often points to underlying conditions like cough-variant asthma, post-nasal drip, or acid reflux. Because the root cause needs targeting, I do not recommend starting specific prescription medications without a proper evaluation. For temporary relief, you can try hydration, steam inhalation, or over-the-counter cough lozenges. However, please consult a doctor. They may recommend tests like a spirometry (lung function test) and might prescribe targeted treatments, such as an inhaler or allergy medications, to manage your symptoms effectively.

These symptoms are common with viral respiratory infections. To manage them, you can try generic guaifenesin to help thin and clear the yellow phlegm, and a saline nasal spray or a generic antihistamine like cetirizine for the runny nose. Staying well-hydrated and resting are also highly effective. Yellow phlegm is a normal sign of your immune system fighting the illness and does not necessarily mean you need antibiotics. If you develop a high fever, shortness of breath, chest pain, or if symptoms last longer than 10 days, please see a doctor for a proper evaluation.

To help with your symptoms, you can take paracetamol or ibuprofen to reduce the fever and ease body pain. For your wet cough, an expectorant like guaifenesin will help loosen and clear the mucus. Drinking plenty of warm fluids and getting rest are also highly effective. Please ensure you follow the dosage instructions on the package. If your fever persists for more than three days, or if you experience shortness of breath, it is best to consult a doctor in person for a proper evaluation. Get well soon!

For nasal and throat infections with chest congestion, treatment focuses on symptom relief. You can take an expectorant like Guaifenesin to help clear chest mucus, and a pain reliever like Acetaminophen or Ibuprofen to soothe throat pain. Nasal saline sprays or oral decongestants can help relieve nasal stuffiness. Avoid taking antibiotics without a doctor's prescription, as most of these infections are viral. Drink plenty of fluids and rest. If you experience a high fever, difficulty breathing, or if symptoms last more than 10 days, please see a doctor for a proper evaluation.

When you cough, the sudden pressure in your airways can force excess mucus from your throat or sinuses out through your nose. This is a very common, normal reaction to respiratory irritation, allergies, or a mild cold. To help manage this, you can use a generic expectorant like guaifenesin to thin the mucus, making it easier to clear. A saline nasal spray can also help flush out your nasal passages safely. If allergies are suspected, a non-drowsy antihistamine like cetirizine may assist. Keep well-hydrated to thin the secretions. If your symptoms persist for more than a week or worsen, please consult a doctor for a personalized evaluation.
