I had an episode the other morning where I began to feel funny and had to sit down.  I developed a cold sweat and could not move my arms.  I was coherent through the episode.  After about 20 minutes I was feeling ok.  This also happened three years ago but was much worse.  I lost eye sight, could not move my body, and developed a bad headache afterwards.
Hello! Welcome on Chat Doctor ! Your symptoms could be related to a TIA (transient ischemic attack). Other possible causes would be low fasting glucose (hypoglycemia), low blood pressure or a seizure. For this reason, I would recommend consulting with your doctor for a physical exam and some tests
