At work this morning I stood up and felt like all the blood rushed to my head, felt really spaced out, saw black spots and felt my legs were weak. Recovered after a few minutes. Since then my head has felt a bit 'heavy'. Tonight the left side of my head feels very strange, almost like a pressure and my left side of the face has felt a mixture of pins and needles/numbness.
I've had migraines in the past but that normally included a severe headache and aura. Could this just be another type of migraine?
