I've just visited my Dad after hip replacement surgery, which he had yesterday.
He's 82 and was in very good health until about 3 years ago when he was diagnosed with cancer. He's now cancer free but the treatment really took it's toll and he's been frail for a while, then a stress fracture leading to the hip replacement.
Last night he was very cheerful, felt well and was in no pain. Today he looks dreadful, really unwell, says he feels very tired but also ill. Also in quite a bit of pain. The physio had him up and walking this morning. His observations are OK, except BP a bit low, but not unusually low for him.
Is he 'just' tired from the op and the physio and the energy going into healing, is this to be expected? He's always been a bit of a hypocondriac, convinced whatever he has is worse than anyone else gets it, but he does look ill.
