Mel, next anaesthetic you have, tell them NO gas. That's the one that made me really sick. The second op he did all inline dose and no gas and I was loads better with no being sick at all. Nerve pain after mastectomy only really grabbed me bad once and it only lasted a few minutes while I uttered a string of expletives. Panadol and Nurofen was ok for the first op but by the second one I was over having pain so they gave me Targin. It has an inbuilt laxative so you don't get bound up. The spiders under the skin feeling does get less over time. I wasn't too worried about it as I knew that was the nerves healing themselves and that's a good thing.
