Hello, thanks for the query to H.C.M.C.
Here I want to make very clear that you need not to fear about this swelling.
You are a patient of asthmatic allergic bronchitis
, that's why there are sneezing
,runny nose , redness in the eyes. Actually all these problems are due to allergy
As far concerned about the swelling it is not serious but you have to keep in mind that this swelling may be due to some infection ( any type , we call this a lymphadenitis
i.e. enlargement of lymph nodes in the neck.
Please consult a physician and get a blood sample , ti will reveal the cause and after this , if need arises you can take treatment in spite of pregnancy
Have a good luck. Dr. HET
