Hello,
Since you have foggy head with nasal discharge and headache, you are suffering from
allergic sinusitis. Sinusitis is commonly caused due to infection in the sinus,
allergy due to dust, pollen, chemicals, fumes, pollution, etc. You can take steam inhalation for relief. Decongestants and antihistamines are effective. Take
Acetaminophen or analgesics, one SOS when required.
You are suggested to get clinically examined by an ENT. Get X-ray PNS done to detect any nasal deviation, so that you can be treated at the earliest. If there is bacterial infection, you will need antibiotics. Stay well hydrated, take warm beverage. Stay away from addictions if any. Take adequate sleep.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
