We dealt with ulcerations on my daughters arm last year and it does break your heart. I second Shannon on asking for the Xylocane. Our doctor wouldn't give us anything topical for pain because they felt it would be absorbed systemically, but did give us Tylenol with Codeine. That never made since to me since Tylenol with Codeine is clearly a systemic drug?!?! She was only 2 months old and I never gave it to her. Once the propranolol was started her ulcerations healed in about a month. It was a long month, but it did get better!
