Tinnitus and loud bangs

All this happened 2 months ago my ears where normal low pitched sound , then i could hear something not right in my ear sounds it sounded like a lawn mowa or loud vibration sound in my ear like it, but i dont know if it was to do with my hayfever season or just the allergies going in to my ear ways and brushing my ear hairs in the ear , then at 3/04/2014 ,i was asleep then suddly i hear a loud almighty bang in my right ear and then 10 mins i heard a diffrent kinda of bang but like a dolly trolly crashing into the wall kinda sound . so thats my experinces with my tinntius

PLEASE REPLY BACK ASP

 

It sounds like exploding head syndrome I had it for a few days. Are you taking any sleep aids? For me stress mixed with melatonin and the zzzquil I was taking seemed to be causing it. Once I stopped it went away.

 

well for me this was 4 months ago my tinnitus was fine low pitch and then it went down to high pitched level and i dont know what has coursed it .

 

So the tinnitus changed after the incident?
