Sprained Back Delayed work

I have been nursing my sprained back and can't work on any sewing machines for right now. I am frustrated and can't do a thing about it. I was already hurting and I lifted one wrong while I pivoted around. I didn't do this by lifting the machine. I have a 9 month old 100 lb. puppy who tried to jump on my lap before I lifted the machine wrong. I ended up at an emergency room. No choice now but to rest it.
