For the past month or so I have noticed that sometimes one of my ears will feel like it's popped (noises sound muffled) and when this happens I have a ringing in that ear. It's always just been either my right or left ear, not both at the same time. Sometimes it comes on for no reason, other times I've noticed that loud noises seem to trigger it. Is this MS, or is it something else? I have a doctors appointment in a few weeks and plan on asking about it then, I just want to make sure I'm not crazy! If anyone has heard of this or has experienced this let me know! Thanks so much!!!!
