I have been having this dull headache in the back right side of my head and ringing in my right ear. The ringing just started. The location of the headache is specific, meaning it doesn't move to the front of my head or act like a normal headache. Initially I thought it could be related to a bed sore, meaning if I rest my head on a surface for extented period of time the pain occurs. I travel for my work overseas to Asia from the Boston area often. At least 9 times a year. I first thought it might be when resting my head in the chair for a long period of time that caused the problem. It would only occur when I flew in business class because of the seat reclining capability. Usually it would go away within an hour. I would also get the same pain when I was home sitting in my recliner. Is it possible that some fluid built up in just that area or something more serious or do I need to have my head examined? No pun intended. Any information would be appreciated.
