What Causes Growth In Size Of Nose Post Multiple Surgeries For Sinus Problem?

Hello sir my name is ashish kaushik,I m a 25 year old guy from New delhi,last year in march one day when i woke up in the morning I was feeling so much pain and some kind of pressure in my nose,so I went for checkup doctor told me its happening because of cold,he gave me some medicines and I took them but nothing happened,then I went to other doctors,one of them told me that I have sinus problem and surgery is the best option for it,he did 4 surgeries back to back on 25th april,2014,its been 1 year now,pain is not that much there but still can feel that pressure,cold all the time but the weirdest thing is my nose is now almost 5 times of its normal size now,it keeps growing,I can t even toch it,1 out of 4 surgery was to make sure that it won t swallow or grow or whatever it is? It grows in width then from the front then in width and then again from the front and that what s happening for the last 1 year,when I asked my doctor why its still happening he said he has no idea,when he failed to help me anymore I went to some other doctors,different doctors saying different things but nobody has been able to explain why its actually happening,they always told me to get back after 2 month so they could see if its really growing or not and when I go to them they say yes its growing but why they don t know,they r even unable to explain the reason behind that pressure...I don t know how to help myself anymore.. I m an educated boy,I have completed my graduation recently and want to study more but because of this not been able to do anything...I know sir whatever I said is hard to believe but its really happening..if u sir can t do anything about it then at least please refer me to someone who u think could help me..please sir help me please.
