Something as common as sinusitis can cause burning sensations in your head. If you've been experiencing congestion, facial discomfort, malaise, low-grade fever and inner-ear pressure, you may have a sinus infection. During a sinus headache, the pain typically hovers around the front part of your head, radiating into the face. The burning or aching sensation is caused by inflammation in the sinus passages that run behind your nose, cheeks and forehead. You may notice that your pain level is higher if you bend over quickly, and you'll probably feel especially bad in the morning after the mucus has collected in your sinuses and begins pressing against the inflamed membranes. If you believe you have sinusitis, visit your doctor. Some forms are bacterial, and a round of antibiotics may help clear up your infection.
