Hello there! Thank you for writing us here. What I suspect is an episode of hypotension which is characterised by symptoms like trembling and shaking of legs and hands, sweating, nausea, anxiety and abnormal sensations sometimes. Mostly people blackout for a minute or two and recover easily. It could be if you skipped your meal or maybe anaemic and several reasons are there. I would suggest you to have a heavy meal and also high carb meal for a couple of days so you have enough glucose in your blood so you won t feel the same again. Eat properly and drink lots of water okay? You ll be alright. Regards, Dr Gunjan
