@loodle have you contacted 13HEALTH? They can give you advice over the phone.
In regards to the codeine, you can take up to 60mg every 4-6hrs which would be your 2 panadeine forte. You can take regular nurofen with the panadeine forte, but don't over do the codeine without speaking to a doctor or pharmacist. Please please call an ambulance if the pain is not controlled. The nurses are very slack for telling you they can't call the doctor in to see you. They get paid to be on call, so they should be there! You may not get X-rays, but at the very least they can prescribe you stronger pain relief. They wouldn't give a phone order without assessing you first.
