I had surgery in April 2013 to remove a cholesteatoma in my right ear and have had regular tinnitus "sea shell" type ringing since. I have learned to deal with this constant sound and it doesn't even bother me and never really has. Around three weeks ago I've had a chugging, whooshing, sometimes like a rumbling thunderstorm sound on top of it. For the first couple of weeks it'd be bad one day for like half the day and unnoticeable the next. Then three day ago a recurrent cholesteatoma was found and removed in-office by my ENT. I thought this new sound was from that because this recurrent one grew really fast over the past month. However, since this "PT" type sound is worse. It's not necessarily constant all day, but seems like it is. I have a bad bout with it for a good half a hour every morning. Then it settes down for a while and comes back when I get home from work like a house of fire when I quietly sit at my computer. If it goes off, when I shift my head like I'm looking at the ceiling it dies down temporarily. If I look down it triggers it. Shifting my head with my right ear pointing towards my shoulder makes it go away temporarily. Doing that thing where you press yur hand againt the ear canal and suction it out makes it stop temporarily. I hear it when I lie down to sleep but I have been able to fall asleep so far without any issue. Any advice would be welcomed with open arms. Thanks! 
PS - I have checked my pulse and it goes at the same beat that's why I think PT.
