Ear problems and disequilibrium due to Botox?

My 7- 8th experience with Botox the last week of Nov 2018. Two days after injected in frown lines /crows feet (crows feet 2nd time). Woke up, cold, achy, headache, plugged left ear and disequilibrium. Today I continue to have ear problems. After 2nd week my right ear also started plugging, unplugging, crackling, issues with temperature changes. I've had antibiotics/ flonase. No relief of the disequilibrium/ ear issues. Is this related to botox? Can Botox travel to inner ear or nearby nerves?
