I was offered exactly this operation, but declined. The consultant seemed keen to do it, but I asked what odds there were of success or failure. He said " 60% improvement, 20% it stays the same, 20% it ends up worse". I thought those were dreadful odds, since the chance of being no better, or worse ( and with a scar) of 40% were terrible odds. The problem has actually got less painful over time, with only the occasional recurrence if I lie heavily on that spot ( mistakenly, in sleep)
You have my sympathies. Hope you are very much better very soon.
