Im 22, 4ft 11, 110lbs. Lately I have been getting involuntary twitches in my arms and legs which is becoming more frequent. Also, my resting heart rate is 114 bpm. I always feel really tired even though I get my 8 hours a night. I suffer from heart palpitations and nightmares too.
Hi, I would recommend going to your physician for some investigations and physical examination as these symptoms especially the tachycardia (increased HR) is actually series and maybe very series. But don't worry you are still 22 and still young maybe you will need some vitamin supplements or so. From your given history personally I will start with T3, T4, TSH blood levels you may have increased thyroid hormone levels. Hopefully not.  Hope the above information helps you. Any further clarifications feel free to ask.
