Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Symptoms to watch for would include double vision, vision loss, weakness of the face or limb muscles, slurred speech, intense headache. Those would be symptoms which might indicate a more serious brain lesion. Otherwise it is more likely to be in the setting of a more benign vestibular issue. Blood pressure should be measured and if symptoms persist some blood tests to screen for issues like anemia which can also cause dizziness are recommended. Hope I have answered your query. Let me know if I can assist you further.
