I think that it is outrageous not to be sent home with pain killers. After all a caesarian section is major abdominal surgery and this would not happen to someone who had an operation for any other reason.
Paracetamol, Ibuprofen and codeine are all safe with breast feeding. You can take then together.
Codeine bought over the counter comes in a low dose combined with Paracetamol. 8 mg (milligrams) of codeine with 500mg of Paracetamol in each tablet. you take two of these every 6 hours. DO NOT TAKE ANY ADDITIONAL PARACETAMOL IF YOU TAKE THIS MEDICINE. It is safe to take this medicine in combination with Ibuprofen.
You can get a stronger version of this from your GP on prescription in a drug called co-codamol. 30mg codeine combined with 500mg Paracetamol in each tablet you can take 2 of these every 6 hours. Again. DO NOT TAKE ANY MORE PARACETAMOL IF YOU USE THIS MEDICINE. It is safe to take this medicine in combination with Ibuprofen.
The safe dose of Ibuprofen in 400mg every 6-8 hours.
Codeine can make you feel dizzy, nauseated and give you constipation. Some people love it, some people hate it but it is the next step up the pain killer ladder as it is stronger than, and works in a different way to Paracetamol and Ibuprofen. If you don't get on with the codeine instead take normal Paracetamol with the Ibuprofen.
Ideally you should be discharged from Hospital with the strong Co-codamol and Ibuprofen. Ask for this.
To keep on top of the pain it is best to take the pain killers regularly and in combination for a week or so rather than wait until the pain gets too bad as they work better that way.
Any problems see your GP as soon as possible.
I hope this helps.
