I was in a shop the other day talking about Dups with someone who said that his friend standing behind had the same problem which he'd just had treated. He'd apparently been treated by the same consultant who told me to come back when I couldn't put my hand flat. The guy who'd been treated showed me his hand which only had 2 small puncture marks in the palm. It would appear that he'd had NA of sorts which was rather confusing as neither my GP or consultant mentioned it as a possible option when I saw them
