I have to agree with others here: pain was nowhere near as bad as I thought it would be, thanks to the pain management - frankly more a discomfort than pain, and the biggest issue for me too was sleep afterwards - I strongly recommend taking some good quality ear plugs to use in the high dependency ward afterwards! (I later discovered my hospital even supplied these in a welcome pack for patients, but as I was an emergency admission I didn't get this). I don't know what it is like in other countries, but here in the UK I find it surprising how little respect hospitals have for the sleep needs of patients. I realise that nursing staff have to do their jobs and the alarms of monitoring machines need to be heard, but noise still seemed excessive.
Pre-op, a nurse said to me "don't be a martyr to pain" - should you find you are in pain, say something and they will give you something to help it, and it worked just fine for me.
