question: for the past few days im having the following problems- I sneeze a lot and my nose gets blocked mostly. It is very uncomfortable in the night.- Mostly in the mornings my eyes start itching a lot and becomes red.- Also there is itching on my face as well and i can see some small swellings (pimple like) on my face.It all started 2 to 3 weeks back and the itching is mostly when Im at home.  Is it the food that Im having that cause these allergies? What should be the course of action that I should take?
