Go to ER: You need to be seen in the emergency room right away. This could be a complex migraine or a stroke. If it is a stroke time is of the essence!

Headache: the issue is , is this is the first time or you have had this before. unilateral headaches can be migraines and can cause neurologic symptoms and can cause hemiplegia (one sided weakness ) temporarily amongst a host of other symptoms. if this is the first time and you are concerned please see your Doctor for further assessment.

This is: a potentially serious symptom and suggests cerebral ischemia (decreased blood flow to your brain) At YOUR AGE (23) it is most likely that it will turn out to be a MIGRAINE variant HOWEVER seek medical help NOW! Begin by calling your Primary Care Office..use a walk In unit or ER if necessary (the last (ER) as a last resort! Hope this is helpful! Good Luck DR Z
