I am writing this from my hospital bed - I was diagnosed with a type of hernia that needed to be fixed asap so 11 days ago I had the procedure to repair it which was not fully successful and today I will find out if I need a further procedure.
My issue is that I am due to start a new job mid-March, I have been told that I would be fine with that start date and would work with recovery period. On Friday I was told I made need a further procedure which would set the clock back again on my recovery and I would need to delay my start at work till the end of March.
I am in tears writing this, I haven't called my new employer as I had every expectation that I was going to be ready to go for the date agreed. I hate letting people down, I am worried about this creating a super bad impression of me, I feel scared 
I will be reviewed later today and no if surgery is necessary but part of me is thinking to just leave it so I can start work as agreed. The impact would be more on my daily quality of life and physical comfort, not on my physical health. I have lived with this problem for a long time.
Prior to this operation my last sick days off were 3 1/2 years (2 days off work following minor op) ago I don't do sick generally (hcp).
Just feel so anxious, I have been trying to give my head a wobble but it is not working...
Has anyone ever had experience of this either as the employer or employee?
