A month after covid, I awoke to severe vertigo (spinning in my head) that caused nystagmus in my eyes for probably 5-10 minutes. I thought it was BPPV, but it wasn't. I ended up with 24/7 spinning vertigo for 5-6 months. Did lots of things in the meantime (P T., saw an ENT, had a brain MRI, lots of lab work, scheduled appt w/ neurologist). I had LOTS of other symptoms that went along with the vertigo (tremors, such severe, extreme fatigue, tingling all over my body, daily migraines began, etc. )

WHAT HELPED? Neurologist found I was low on ferritin, so she had me begin taking iron every other day. My vertigo then began to be more intermittent. Another neurologist said I'd had Wernicke's encephalopathy which had left me with brain damage which could be permanent. I finally also was referred to an immunologist due to low immunoglobulin M, but he's the person who REALLY helped me! My 3 brain MRIs all showed "moderate mucousal thickening" and two mucous retention cysts in my right sphenoid sinus. So, he had me begin a sinus regimen that has almost kicked my symptoms to the curb completely ... after 13 mos of suffering! I now do a daily sinus rinse with NeilMed products. In the morning & at night, I use 2 sprays in each nostril of Azelistine 0.1% (aka Asteline). During the day, I take 2 sprays in each nostril of OTC Fluticasone (aka Flonase). At bedtime, in addition to the Azelistine nasal spray, I also take 2 pills: OTC 10 mg Cetrizine (aka Zyrtec) & 10 mg montelukast (aka Singulair).

I started breathing better the very first night I used the montelukast! And my symptoms have VASTLY improved in the 2 months I've been on this regimen! The brain fog and vertigo feeling in my head is nearly completely gone now!

I hope and pray that this info can help someone else. Blessings, all!
