Hello, In my opinion, your dizziness may not be related to PRK laser eye surgery done a month ago. The following are few probable causes of dizziness or lightheadedness: 1) Vertigo 2) Cervical spondylitis 3) Severe anemia 4) Postural hypotension or decrease in blood pressure when you stand up from sitting or lying down position 5) Low blood sugar or hypoglycemia 6) Heat exhaustion 7) A viral infection of vestibular nerve which helps in balancing 8) Migraine 9) Certain medications like antidepressants, sedatives, blood pressure lowering medications 10) Anxiety disorders 11) In rare cases, heart conditions like cardiomyopathy If the dizziness spells are associated with any of the below symptoms, you need to consult a physician as early as possible: - Sudden, severe headache - Chest pain - Difficulty breathing - Numbness or paralysis of arms or legs - Double vision - Rapid or irregular heartbeat - Confusion or slurred speech - Stumbling or difficulty walking - Ongoing vomiting - Seizures - A sudden change in hearing - Facial numbness or weakness If any of the above is not present, it can be considered as mild dizziness and causes mentioned above are to be ruled out. It s better if you can meet a neurologist and discuss your problem. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Pallavi M., Anesthesiologist
