Can long-term untreated headaches cause tinnitus? I have been experiencing headaches on and off for a long time. I never consulted a doctor, so I am not sure what type of headache it is. I also have tinnitus in one ear. My questions are: Can long-term untreated headaches cause tinnitus (ringing/buzzing in the ears)? If yes, which types of headaches are most commonly associated with tinnitus? My headaches come and go rather than being present continuously. Does this pattern fit migraine or another headache disorder? Thank you
