Nasal Congestion
One of the earliest symptoms of sinusitis is nasal congestion, where your nasal passages get narrowed when they are swollen or inflamed due to infection. This usually makes breathing difficult. In some cases, you may also find it difficult to sleep comfortably at night. Contact your doctor immediately if you find it difficult to breathe when sleeping.
Dizziness
If you feel stuffed up or extremely congested, you may feel like mucus is blocking your nasal passages and adding weight to your face. The extra weight may make you feel heavy and throw you off balance, so you have to tilt your head forward or move around to stay comfortable.
