Yes, I would say you have vertigo. I had covid in Aug. 2021 and felt dizzy at the time. But month later is when true vertigo kicked in. In the middle of the night, as I rolled over, my whole world was moving. It woke me up several times and I forced myself to go back to sleep to avoid that awful feeling. I assumed I would feel better when I woke up, but I did not. Instead, when I woke up, it felt like I was spinning as I laid in my bed. I thought it was BPPV because my twin sister had gone through BPPV in the past. What I didn't realize is that the word "parixysmal" in BPPV means it's epusodic. My vertigo was not episodic. I had extreme vertigo 24/7 for 5 full months. It was awful. I couldn't watch the water flow into the bathtub, I had nystagmus in my eyes that first morning. I had tremors, disorientation, incoordination, tingling all through my body, such extreme weakness & fatigue that I would wake up moaning every morning. It was so hard to force myself to get out of bed each morning. I barely had re strength to hold my toothbrush and forget the hair dryer. I had to let my hair air dry. My vertigo was so bad, as I used my electric toothbrush, I would accidentally hit my teeth with the hard casing of my toothbrush instead of the bristles. I had the most excruciating headaches in the back of my head. I had to put pillows under my neck so nothing would touch the back of my head in bed. My eyes were almost always red. My dr referred me to a physical therapist who tried the BPPV exercises (which I'd already tried at home ... to no avail). By the 3rd PT appt, my PT & I both knew I needed a referral to an ENT/audiologist. By this time, I had quit driving and using stairs. I'm 57 and was otherwise healthy before all this but my husband had to start chauffeuring me around (to work, to dr appts, etc). I could barely walk and began using a cane, but the cane really didn't help because it took additional coordination to use it, which I did not have. I even tried a walker, but again it made me weaker to use the energy to move the walker & it really didn't work well with my uncoordination. It got so bad, there were a couple of times when my feet just wouldn't move. I was so scared, I started crying! I thought I must have a brain tumor that they hadn't yet discovered.

The ENT said my hearing and ear pressure tests were perfectly normal, but I needed balance testing and a referral to a neurologist. It took forever to get in to a neurologist.

When I finally saw a neurologist, she told me my ferritin was low which can cause "all sorts of neurological issues". So, she had me start iron which I take every other day. She also gave me a nerve block shot in the back of my head for my daily "migraines" which she said were actually occipital neuralgia. This neurologist said my MRI showed I'd had a stroke but not in an area that would explain my vertigo, wide-based, slow, ataxic gait, or incoordination. The iron began helping and my vertigo finally began to be more episodic (3-4 bad days followed by 3-4 good days at a time).

I was in PT for 3 mos, until I was no longer improving. I saw another neurologist who had me do another MRI. She said the 2nd MRI didn't show that same spot that had been determined to be a stroke, so I had definitely not had a stroke. She believed my inability to eat any food or keep even vitamins down for nearly 2 weeks with covid had caused my thiamin level to drop too low, causing Wernicke's encephalopathy which can leave a person with permanent brain damage. However, that didn't explain the fact that my vertigo, tremors, headaches, uncoordination, fatigue, etc were now coming & going. It was no longer constant. My neurologist admitted that brain damage wouldn't come & go like that.

We did all sorts of tests (EKG, EEG, 3-day heart monitor, 5-day in-home EEG with video monitoring 24/7, EMG nerve conduction study, lumbar puncture, blood work). Nothing really showed up.

But I kept getting various infections & fevers after covid (diverticulitis, sinus infections, tooth infections). My Immunoglobulin M showed up as low and I read that could cause me to keep getting random infections. AND I got covid AGAIN! So my PCP & my neurologist both suggested I see an immunologist.

The immunologist/allergist did more for me in the 10-minute telemed appt than all the other specialists I'd seen the entire 12 mos prior! I read some of my MRI results to him, which talked about moderate mucousal thickening in my sinuses along with two mucous retention cysts in my right sphenoid sinus and also in my ethmoid sinus. I didn't know it yet, BUT MY SINUSES WERE CAUSING MY VERTIGO & OTHER SYMPTOMS!

My immunologist has me on a sinus regimen that has helped me get back to almost normal now!

Since you had a lot of sinus issues with your covid, perhaps you should see an immunologist/allergist, too? Maybe that's causing your issues.

In the meantime, you can start a sinus regimen with OTC mefs and see if they help. They won't hurt you anyway.

Each morning, I use a NeilMed sinus rinse (aka "netti pot"). Then, I use a prescription nasal spray (Azelistine/Asteline). After work, I use 2 sprays in each nostril of OTC fluticasone (Flonase). At bedtime, I use my Azelistine nasal spray again and take 2 pills: 1 OTC cetirizine (Zyrtec) and 1 Rx montelukast (Singulair).

Good luck, dear. I pray that your anxiety will be decreased and that some of these suggestions may help you.
