hi i had gone through your query and understand your concerns. i would come up with the possibility of ALLERGY
may be the underlying for your sufferings.
Allergies are defense system over-developed by the body to give warning that its metabolic system is unable to handle a substance in a normal manner.
-inherited influences;family history of similar allergy complaints may confirm the diagnosis.
-pollution of air and water
-excessive consumption of starchy and sugary foods and milk
are other possible causes
I hope this is helpful for you, thank you
