This happened for the first time today....I woke up and to the bathroom because my stomach on the right side was hurting....i started feeling a little dizzy and faint like but went to the bathroom when i stood up my head got a rush and my vision became blurred so i grabbed onto the counter and just held it i became to sweat and felt overheated so i put water on my face i was so hot! then my arms and legs began to shake uncontrollably for about 30 seconds i was still holding on to the counter then turned the shower on and got in chilly ish water to cool my self down... all day i have been shaky
