Glad you mentioned this. I have chronic pain/fatigue so for my lumpectomy I announced I was going to bed for a week (well, I include some exercise and puttering and reading but mostly DOWN). I knew I wasn't going to bounce back after three days, because frankly a flare can put me to bed anyway. Count in anesthesia, trauma, pain and stress and I knew I needed to take it super easy. I think in your case the fibro is an important factor--not to give up on improvement but take it slow. A week is not that long to recover--watch out for fever etc. or anything worrisome post-op--but I think you can give it some more time before being too concerned. Of course check in with your doc as needed. Happy holidays--hope yours are peaceful and healing.
