Lump under left side of neck under ear,always feeling pressure in that part,Grey or yellowish sputum is produced in throat esp,. after having food. What should be done? Hello Doctor, I have a lump on the left side of my neck, just under the jawbone and my ear.Though its not visible outside, I can feel it when I touch.It is firm and not painful unless I keep pressing on it. I have a pressure feeling in that ear, and quite a lot of sputum(Grey or yellow) is produced in the throat esp, after having food(Sometimes I see blood strains in that).Most of the time I feel feverish and tired.But if I am involved in physical acitivity I feel quite normal. I have consulted lot of doctors with tests like blood,sputum,x-ray,USG. They said the results are normal.But their medication doesn t solve my problem.It s been there for me more than a year now but not getting any better.These is causing lot of mental stress for me so that I can t concentrate on my work.can you please tell me what to do?
