Hello,
There are a few of us fibro sufferers on here, although I think most are early days post or pre op.
I have fibro along with a list of other things. The surgery made a huge difference very quickly. I had a good recovery, and my general pain levels decreased dramatically very soon post op.
Since the surgery, I've only had one fibro flare. It lasted a couple of weeks instead of a couple of months and I managed to work through it.
Also since the surgery, I have only taken painkillers a couple of times, and only paracetemol. I was on dihydracodeine daily pre-op.
I have IBS with the fibro, and that has pretty much gone. Only a couple of attacks in the 10 months post op rather than a couple a week pre-op. Previous trigger foods such as wheat and dairy are now fine too.
So in short, for me it didn't affect my recovery, and has been vastly improved very quickly.
