Hi I had a full left nephrectomy on the 15th September 2023.

I have had spells of really light headedness and trouble catching my breath, sometimes together.

Yesterday I noticed one of the keyhole dressings has a green/brown stain in the middle (only small).

I phoned 111, explained and they have just phoned me back, but didn't seem to bothered! Just telling me if I feel worse to phone back or see gp tomorrow. 

My question is, is the light headedness normal after a full nephrectomy and if so what can I do to help ease it and how long does it last? Also should I be more worried about the wound? 

I have no temperature and the area is only mildly sore. 

Thank you
