You should go to see your doctor for a full exam to figure out what's going on.
Hemiplegic migraine can be hard to tell apart from other conditions, like stroke or mini-stroke (also called transient ischemic attack). Its symptoms can also be similar to diseases like multiple sclerosis or epilepsy.
A CT scan or an MRI of your head can show signs of a stroke. Tests of your heart and the blood vessels in your neck can rule out symptoms caused by blood clots.
If you have a family member with similar symptoms, your doctor may want to do genetic testing. Familial hemiplegic migraine (FHM) means it runs in your family, and you could pass it on to your children. People who don't have problems with those three genes have sporadic hemiplegic migraine (SHM).
Doctors disagree over how to treat hemiplegic migraines.
Your doctor might prescribe drugs to prevent hemiplegic migraine, to stop them once they've started, and to relieve your symptoms. Your doctor will discuss the best options for you.
In addition, the migraine triggers must be identified and avoided. Each person may have a different combination of triggers. It is very helpful if you keep a migraine journal that records your migraine symptoms, what time of day you experience them, what occurred before the symptoms began, how long they last and the severity. This will help you identify and later avoid your migraine triggers as well as accurately diagnose migraines.
You should avoid using over-the-counter drugs which may do harm to your disease.
