I had knee reconstruction surgery one month ago. The surgery is successful, but I have been constantly nauseous since. I have an infection over the surgery site - redness, heat, swelling - and my GP has put me on a 2-week course of flucloxacillin. Unfortunately, this is exacerbating the nausea. Even tho I am also taking cyclizine to combat this, I am constantly miserable and unable to function normally even for one complete day. Is there a way out of this?
