Hi Thank you for asking HCM. I have gone through your query. Your problem can be due migraine. As MRI is fine your brain is with out any serious problems. A consultation with a neurologist is well appreciated. If neurologist insist then you have to do an ecg also. For migraine two types of treatment will be needed. One is preventive medication which is an anti epileptic or anti depressant. This will decrease the frequency of attacks. Other type of medication is while you getting symptoms of migraine. This can be paracetamol with domperidone. Also avoid any provoking factors for an attack. Mostly it will be hard physical exertion , high exposure to hot sun , stressful conditions etc. Hope this may help you. Let me know if anything not clear. Thanks.
