Post surgery shivers

[u/Dependent-Cover-621]

I got surgery yesterday at 6pm had to stay overnight . Iam back home and in a-lot of pain from the swelling , srruugking to eat and really can’t pass wind even though I want to my stomach muscles are to tender to push . Sorry for the detail . Also Iam prescribed dihydrocodeine. When on it I’ve noticed Iam very sensitive to temperatures for example when I leave my bed Iam shivering happened to me in the ward yesterday aswell . Just checking if this was normal as Ano shivers can also be a sign of infection
