Being woken in the middle of the night with terrible pain to my ear!!!

This is very odd and I've not been able to find much research on it except an old post on a pregnancy forum. Each night since I found out about being pregnant I've been sleeping on my left side. Well a few hours after falling asleep I'll wake up with this tremendous pain in my ear, more the outter ear, not like an ear infection...and its sooooo painful I have to slowly move my head away from my pillow, and I mean slowly bc the pain is so bad. This does not happen to my other ear when I lay on my left side, and has only started since I've become pregnant (put 2 and 2 together after finding out about the pregnancy)....does anyone else experience this? The pain is horrible, only last for about 15 minutes once it wakes you up but it's not a very nice feeling to be woken up to and really messes with my sleep!!! Please tell me I'm not the only weird one out here experiencing this!
