Hello,
What you're describing happens commonly in people with viral infections of the ears,
sinuses, or upper
respiratory tract.
Since you didn't say anything about
nausea or
vomiting I'm assuming that's not an issue and that is good news.
However, if she is unable to stand or move due to the
dizziness and she continues to have these symptoms even when lying down then, I think it best she be seen by a doctor in an Emergency Room.
Make sure you give her plenty of fluids to drink if she is not able to easily get up, call her doctor and then, follow their instructions.
If she starts to have nausea, vomiting, or has trouble with her speech or doesn't seem to understand things because she's zoning call 911 immediately.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Dariush Saghafi, Neurologist
