Hi hun, I think I’ve got the same at the very bottom of my lollipop scar but a bit smaller of an area. White colour is a good sign as it’s just the antibodies protecting the open wound. I wouldn’t worry too much, as worst case scenario you can just get some antibiotics as a precaution from the clinic. I covered mine with a spare dressing I had and going to mention it to the nurse at my appointment next week. Try not to worry and contact them on Monday, hope all is well! X
