Hi, My symptoms started 6 weeks ago with a muffled, stufffed, and pain in the ear. Long history of ear infection, sinus surgery etc. was treated for ear infection. Pain in the back of my head when bending over, straining, coughing etc. Saw an ENT. After passed hearing test etc. Gave me nose drops for enlarged adenoid which can affect hearing. Have a follow u in 3 weeks. Only symptoms is mild tinnitus which I didn’t have when I saw the ENT and the sharp pain to my head. Only one side. Could this be AN? I have been searching online and besides AN found that maybe it could be a blocked nerve or occipital Neuralgia. Has anyone experienced pain in the back of the head?
