Yes the nausea and fever are present, so this looks to be the most likely cause, in my opinion. I'll take it from here.
Not impressed with the service so far, like many in your profession, you jump too easily to conclusions, if you don't mind me saying so.
Fever is quite high, soaked her bed with sweat last night. Had to change all the bed clothes. Legs painful ankle to now just above the knee, fitted tight stockings which gave some relief. But overall much better than yesterday. Will not allow me to call for an ambulance, so press on at home. Pain in scalp easing, so I think my wife is on the mend. Least ways l am praying that is the case.
Much better today, about 50% there, I think. Washed and cleaned everything up and assisted with wife's shower, so feels a bit better, but lower legs still ache and she had a mild fever overnight.
About two weeks ago my wife had minor surgery on her forehead to remove a rogue mole and was discharged without any dressing on a 50 mm wound. I think that's when the infection first got in. She has been feeling ill every since.that time and the wound is still tender to touch.
So as a consequence she will not go back to hospital, as you come out with more than you go in with, so to speak. BP today 110/79 pulse 78 not perfect, but within range.
