I'm not aware of your whole story here...still new and I could read for years but can't sit that long at the computer..
But I sure wish you a speedy recovery. It certainly doesn't sound very comfortable and I bet your Mom would rub some lotion onto your back for you! I had the same problem with that anti-b soap with a surgery I once had too...the nurse was so nice to rub lotion into my back in the hospital and it felt SO good...
Take it easy
