Hi CattyB - I am so sorry to see you joining us here, but you're in the right spot for support and ongoing information re your treatment xx
If you still have a cough/lung issue, I would suggest that you ring the hospital today (that you are booked in for surgery tomorrow) - and ask their advice. Normally, if you are still unwell, it would be cancelled & rescheduled. They normally don't like giving anaesthetic to anyone with lung congestion.
I hope you are feeling better soon & can go ahead with the revision surgery xx
In the meantime, feel free to check out this link that has lots of info on the forum & various groups that you may like to join, or subjects you'd like to comment on.
