Welcome to HCM!
I have gone through your question and form my clinical experience I can say that your presentation can be due to varied reasons ranging from simple falling in blood sugar levels ( as it happens when you don not eat) to some digestion problem to a case of seizure disorder
. One needs to evaluate you throughly before prescribing you anything.
had I been treating you, I would get your sugar leves, both fasting and PP, thyroid
, liver, kidney
, lipid profile
, an ultrasound
abdomen. if everything is ok, then getting an EEG will help to find if there is a. case of seizure disorder ( as you have a shaky feeling, then strong headache, and later you feel sick and then go to sleep) , this is a strange presentation for any gastro-abdominal cause.
Theer is no need to panic, but please. see a doctor and get your self checked at least once.
please avoid staying hungry for long hours, by this you may help in preventing another attack.
Hope you get better
Dr. Manisha Gopal.
