I am a "certified floor inspector" I fall about once a day, at minimum. Some days I fall so often my husband orders me to stay put, as he tired or sore from helping me up.

Inform your doctor since this is new. {if you have a PT} Have your PT person teach how to fall safely (yes, there a technique). Sort of tuck and roll maneuver.

and... hope this is something minor like allergy causing some inner ear goofy-ness and it all goes away fast.
