Hi, Welcome to Healthcare magic,
Interpreting from your clinical history, which you have elucidated well, it is clear that you are having "Sympathetic overactivity".
The sympathetic system is part of the Nervous system that gets activated during any sort of stress- 1. Psychological : extremes of emotions- excitement, anxiety
, panic, sudden happiness, etc such situations arise when in danger, threat to life, etc
2. Physical : hunger(hypoglycemia
, excercise, child birth etc.
Now it so happens that some people have a hyperactive Sympathetic system. This has been observed to be familial in many cases.
This hyperactive Sympathetic system, could be of two types :
Primary- which can occur at any time for no apparent reason, however the suggested trigger factors include eating spicy foods and excessive alcohol or caffeine consumption.
* Low Blood Sugar
* Overactive Thyroid
* Severe Psychiatric Disorders such as major depression
or severe obsessive-compulsive disorder
* Any Type of Cancer
* The Use of Certain Medications
Your case could fit a diagnosis of :
1. Primary Sympathetic overactivity/ Hyperhydrosis
2. Hypoglycemia-low blood sugar levels/ Diabetes
4. Sun allergy
