Your body has been through a massive ordeal and it was only a matter of a couple of days ago, it will get better. You've had a massive shock to the system.
I didn't get wind pain after the op, although I expected to. Try some peppermit tea or Rennie/wind-eaze kind of products that dissolve on your tongue, they have all worked for me in the past. People have previously posted that moving about helps ease any trapped wind. Good luck sorting it quickly x your first bottom burp is always a bit scary with internal stitches!! you will be fine though.
Didn't the hospital give you any anti-nausea medication? If you didn't get any perhaps you could contact them and ask for some if it is a real issue - feeling sick is horrible and it can be eased.
I was being quite sick for a couple of days post op, the morphine in the hospital was the culprit for me. I did feel horrible for the first couple of days and regretted the decision - but that was because I was feeling sorry for myself and had a drain connected which kept leaking, cannula in the wrong place which blew my arm up like a football and nobody noticed despite 30 minute obs ........ oh, what a drama!
Nanny, it gets better and better - I promise! when the stuff they pumped through you during the op gets out of your system and you get a bit stronger (from all the rest and nurture you should be treating yourself to) you will look back and say 'this was the best decision I ever made'
Welcome to the other side - I look forward to all your updates x
