Symptom #4: Congestion
Our airways need to be kept clear in order for us to be able to breathe. There needs to be enough space for the air to pass through and this is not usually a problem for us at all. When we have a cold, though, then things can get quite congested in the airways.
Congestion is usually caused when the membranes lining the nostrils become inflamed, restricting the space available. A buildup of snot in the nostrils can also contribute to this. The good news is that there are remedies available on the market that can help to ease congestion.
