My name is Brenda and I have been experiencing ringing and a high frequency sound in my ears. however when I take Benadryl, the ringing and high pitch frequency leaves. I can also feel some relief in my ears. I was told that I had Tinnitus but when I take Benadryl I feel relief. Why is that. I went to my doctor and she told me that it seemed as though allergies were the culprit, and will I have to continue to take Benadryl when the ringing returns because I feel so much better when I take it and the ringing in my ears go away.
