No it's YOUR Sciatica

So...my back hurts. I'm not entirely sure what brought this on. I did feel pretty sore when I visited my parents and slept in my old twin bed for a few nights. It also gets a little hairy when I'm at Boyfriend's and the cats are there:

It's not easy to squeeze into that side!

But either way, I woke up a couple days ago and my back hurt. Bad. 

The pain is shooting down my side and leg. Not good. 

Boyfriend told me I had to do this thing called "stretching."

Honestly how dare he.

So, I've been heating and stretching and standing and sitting for a couple of days now. Hopefully it'll get better soon. Sciatica relief tips, anyone?
