Hello and welcome to HCM.
I have gone through your query and understand your concern.
Considering the clinical scenario you described,I feel it will be first necessary to find out the underlying cause.Subsequent action to be taken depends on the cause.
You can give something with sugar put in it as it can be due to
hypoglycaemia.
Certain medication or food (especially fish)may cause such complaints as as
allergic reaction,so I need you to review any recent change or intake of medicines that coincided with this symptom.
I advise certain blood investigations like blood
glucose,serum Vit B 12,serum calcium levels.
Besides,I would like to ask you what is your occupation as certain chemical exposures like mercury at workplace may be associated with such picture.
You can be back with me here for further clarifications and query.
Thanks and regards.
