Hi, I have been experiencing some swishing pulse like noises in my left ear since about a week. I recently had a surgery done on my ears where the Dr had to put tubes in my ears. Is there any reason for me to worry about these sounds? I remember, I was told by the Dr that I would still hear ringing sounds in my ears after the surgery but will get used to it with time. Well, it has been almost two and a half months, since my surgery.
