Dear doctor. I'm 19 years old. I have a very bad head pain like my head is about to blast that much pain. I have been noticing that I have an extra growth on my left side of my head. I had it from childhood initially from past 6 months it started growing to a big size. Two weeks back I went to forte hospital In Bangalore and took a x-ray CT scan of my head doctor said surgery need to be done so two days back I had a surgery and now the swelling has increased is it because of the stitches or something else doctor?
