Sudden hearing loss in one ear?

I woke up last night to the sound of rain. I rolled over on my left side and realized I could barely hear it out of my right ear. It's pretty significant on the right side and I'm not sure how long it's been like this.

I'll be Googling it here in a second but wanted to know if anyone has experience something similar. Phone Post 3.0

wax build up.

Yeah, this happened to me and it drove me crazy for 2-3 days.  Went to the Dr. and had my ear irrigated and the feeling of relief was amazing.

 

I just blast the shower into my ears at close range. Usually sorts it out.
