I still remember my cousins’ long nights without sleeping. She was only 2 years older than me & had severe allergy/sinus symptoms. Nothing seemed to alleviate her pain. I wished I had the magic potion that will cure all her afflictions. She suffered often from uncomfortable sinus headache symptoms. Most patients with the common cold show sinusitis symptoms: fever, headache, congestion, facial pain, pressure, or fullness, ear pain, dental pain etc. Many primary headaches might resemble sinusitis headaches.  There are two types of sinusitis, acute (sudden onset) and chronic (long-term). Occasionally sinus symptoms mature into bacterial infection. Mucus fabrication obstructs the nasal passage and bacteria jumps in. Sinusitis seldom becomes severe & when it does antibiotics generally stop it from going that far. It’s just so uncomfortable and painful. I have never suffered from it but still think about my cousins’ agonizing face… Antibiotics kill bacteria and prevent infectious organisms from reproducing. Anti fungal medicine, decongestants, and corticosteroids can also help. Contact your doctor when looking for the right medicine. A good-professional advice might help.
