Hey everyone, I'm new to the message board and posted on the other forum, but thought my symptoms might fit better over here. I'm a 27 year old male in great physical condition with sudden sensorineural hearing loss in my right ear that came on unexpectedly 2 years ago. I had an MRA to rule out anything abnormal and it came back clear. ENT specialist said these things happen sometimes as they never figured out the cause. I have been able to come to terms with the regular tinnitus and go about my life. The reason for my post is in regards to something I've been experiencing even before I had my case of SSHL 2 years ago. Basically, whenever I'm exercising or I raise my pulse rate, I hear my heartbeat in my head. It sounds mostly like it's inside my head. I can't pinpoint if it's actually from one of my ears. It's mostly a "thud.. thud..thud" sound in sync with my heartbeat. I notice it when I stop running or finish a set lifting weights. It last for 20-30 seconds max until my pulse returns to normal. I've always thought this was normal and that everyone experiences this when exercising or doing a strenuous activity. I've had this anomaly for as long as I can remember. The noise doesn't effect me otherwise, as it only happens when exercising or sometimes getting up to quickly from laying down (which sometime causes a 5-10 second whooshing sound then disappears). My fear over this lies in the vascular components I've read on google. I'm nervous there could be a problem with a vein or artery that's causing this. Is this something I should be concerned about, or is my anxiety getting the best of me? I appreciate any insight!
