Headache due to sinusitis

Would like to share my case….

I got severe headache last week with mild fever around 100. I didn’t do RT PCR but assuming COVID started with low dose antiviral combo, homeopathy ferrum phos, bryonia and tablet Imusil. After 2 days there was no fever. Fatigue was also improving with Imusil.

Now after 5 days only problem was severe headache behind left ear. Headache used to increase after food and after positional changes. I took homeopathy lachesis and conium yesterday. Today headache has completely vanished — this headache was due to sinusitis.
