Why do I have frequent runny nose relief temporarily?

A fever and headache usually tell you that the body is busy throwing away an infection from it, such as a cold virus. Consume plenty of fluids, take rest, and you can also take “over-the-counter” pain relievers such as acetaminophen or ibuprofen to help with a headache and fever. Besides, soaking in a warm shower or using a humidifier will resolve your stuffy nose too. If the symptoms worsen consult a doctor.

You could be suffering from rebound congestion. This is common when people use nasal sprays such as Sudafed for more than a couple of days. It may cause you to have swollen nasal passages with a feeling of being more congested. The saline sinus rinse is excellent at relieving the swelling. It's best to avoid overusing the nasal spray to prevent rebound congestion.

It appears you are going through allergic rhinitis, which is responsible for your runny nose, swollen eyes, ear pressure, sneezing, and breathing difficulties. These symptoms have been persisting for a long time despite trying different medications. The allergy shots that you are receiving may have expired, thus not giving you enough relief. Seek consultation from an allergist to review your treatment plan and consider updating your allergy shots to manage your symptoms effectively. 

The pink fleshy parts you see are likely normal structures, but they may appear enlarged during congestion. This condition can improve over time. To alleviate symptoms, try using saline nasal sprays, staying hydrated, and inhaling steam. If symptoms persist or worsen, seeing a healthcare professional for a thorough evaluation is a good idea to rule out any underlying issues and receive appropriate treatment.
