Thanks for the query to H.C.M. Forum.
All the symptoms , which you mentioned in your query seems to to be due to food allergy
, milk products are responsible for such type of allergy as you mentioned that when something eats , there develops heaviness in eyes .
This is an indication that, you have food related allergy.
Swollen legs and puffiness over face ( next day) are an indication of either allergy or due to involvement of KIDNEY
Consult a physician and get in blood examination for sugar, lipid profile
Hope I have answered your question.
If further any question.
