Has anyone’s LO experienced vertigo and dizziness?

No answer to your question as such but
as long as the person hasn’t heart issues a little ginger in their tea helps calm the dizzy sickly feelings
sorry not answering ur question but maybe help in managing the awful symptoms

Could be anything including inner ear problems.
Whatever it is, this is in the purview of medical diagnosistics.
I wouldn't start guessing; it's time to see the MD.
Good luck.

I should have mentioned that his vertigo happens when he lays down. He gets dizzy at various times.

Usually when someone has their first episode of vertigo, they need to figure out what is causing it: inner ear infection, Menier's disease, tumor, etc. If it's none of the many identifiable causes, then the diagnosis settles on BPPV (benign paroxysmal positional vertigo), which is what I have had on and off since 1989.

I find the worst part of my vertigo is the nausea. Meclazine makes me too drowsy to function, but is OTC an may provide your husband relief (but he will be sleepy). I have a prescription for Zofran, which is an antiemetic and helps me a lot so I can function even through the dizziness.

I wish you success in getting it diagnosed.

My dad had repeated bouts of severe vertigo, lasting about a year. After multiple doctors and tests, we ultimately found an excellent physical therapist who was exceptionally good at the Epley maneuver. Seems not everyone has equal skill at it, or at least that’s what we found. The good PT worked with dad a couple of times and it never returned. Hope you can find someone helpful, it’s beyond frustrating

My mother had severe vertigo, and vascular dementia as well, but the vertigo was attributable to neuropathy in her feet, combined with poor vision and hearing. With loss of the feeling in her feet, combined with the other sensory losses, she had no idea where she was in space. That's what caused her vertigo. I'd take her to the ENT doctor who would do the Epley Maneuver on her and she'd feel better, combined with Meclizine which is the standard drug (otc) for vertigo. It disappeared for her once she went into a wheelchair fulltime.

While vertigo is not associated with Alzheimer's, a pretty large number of dementia sufferers DO develop it at some point, oddly enough.

Your husband should definitely call the doctor to see if Meclizine is recommended as a treatment so he can get some relief. Vertigo is very unpleasant.
