ouch...help?

[coffeetime]

I've done something horrid and strained a lat muscle. It hurts from the back of my ribcage all the way around to the front. I know enough not to lift until it eases up, but everything makes me wince--even sweeping the kitchen or picking up a bag of groceries! Even walking is uncomfortable and I definitely can't run. At the gym I've had to do the elliptical (only) since that has the least impact.

I've tried foam rolling. Excruciating in the moment and afterwards I just feel more sore. I've also tried a heating pad, warm bath with epsom salts, and yoga. Anything I haven't thought of? (My massage therapist is busy until Saturday.)
