My 4yo son had surgery a week ago. We stayed 1 night in hospital. The nurses gave him both Paracetamol & Nurofen together 1st thing in the am & last thing at night in order they said to control the pain at its worst times. I have carried this on until yesterday, as well as giving x2 doses of Calpol during the day. I am now very concerned after reading conflicting reports about giving these 2 meds at the same time. Just praying I haven't done damage to my son. Was just following instructions given by the hospital... His pain has reduced enough now to be on Calpol only.
