I am a nineteen year old female. For the past few months I have had muscle twitches frequently each day. I saw my doctor who tested my potassium and magnesium, potassium was 3.8 and magnesium was 1.8 which was in range on the labs but I don t know what is causing these persistent twitches. I have been to a cardiologist and neurologist recently who gave me a clean bill of health. I have Hashimoto s Disease & PCOS but other than that I am healthy. I drink a lot of water and electrolyte based drinks but nothing is helping.
