How can i reduce severe headache caused by omicron virus, my head feels like it's gonna explode

You may take acetaminophen/paracetamol. No more than 4 gm in one day. No alcohol. Drink enough water so that your urine is mostly colorless, If this does not resolve the issue, please consult a doctor in-person. Get HPV, Flu and Covid vaccines. Wish you good health!

Headaches can be triggered by COVID-19, and omicron variant would not be an exception. If migraine has been previously experienced and/or runs in your family, you may need neurological attention, if this becomes a specific pattern. Contact your doctor if OTC remedies fail to help.
