Respected doctors ,I met with an accident 11 months back. The other person was also taken to the hospital. We both got admitted. Doctors found out that the other person is positive for HIV. So they advised me to do hiv test after 3 months as there was lots of blood exchange and loss. I was discharged after 3 days. I was so tensed ,worried and anxious. On 5th day I could?t even swallow anything. I felt something was struck in throat. I felt As if a table tennis ball was sitting on my throat. So I rushed to the gastro dept, where endoscopy came out normal. Now it?s been 11 months I still have that feeling ,lump kind off. Is this serious? Can it be cancer? How come my endoscopy was normal?
