Hi, I’m an Audiologist (hearing and balance specialist).
There are many things that could cause these symptoms; such as environmental allergies, blood pressure or glucose fluctuations, migraine (aura without headache), dehydration, nutritional deficiencies, lack of quality sleep, medication side-effects, stress/anxiety/depression.
If you are generally healthy, increase your fluid intake and reduce/avoid alcohol and caffeine. Make sure you eat well and get plenty of rest over the next few days, and maybe go for a walk or do some yoga or meditation. See if that does the trick. If not, see your Doctor on Monday.
I hope you feel better soon!
