Fasciculation male, 23 I have been sensing sudden pulsating rythmic muscle movement not very strong but I can see my muscle pulsating and also feel it since 1 day. It happens only in upper half of right forearm. Its adding to my existing stress and worries. It lasts for a few seconds only and occurs after 5-10 mins. My history I am having stress and anxiety since lockdown I have recently started gym. Half a month ago. No other disease but on medication for irritable bowel syndrome. The medication is normaxin rt (taken only for a few days) should I stop taking it.
