[|AI|]  Hello! Welcome on Chat Doctor! Regarding your concern, I would explain that your symptoms are related to the changes in pressure. It is normal to feel that way, after these changes. Anyway, if your symptoms persist, I would recommend consulting with a neurologist for a careful physical exam and some tests: - a brain MRI - complete blood count, PCR, ESR for inflammation. In the meantime, I recommend you to closely monitor your blood pressure values. Hope to have been helpful! Feel free to ask me again whenever you need! Kind regards,
