Yesterday I had a needle biopsy. Last night it was a bit itchy and this evening it got very itchy so I did as instructed in the letter and removed the waterproof dressing. It's gone red where the dressing was underneath my boob as the biopsy was taken from quite low down. The actual stitches and look fine and it's not super sore but I'm a bit concerned about the redness. Is this likely just a reaction to the dressing or do I worry about infection? I'm going to call them on Monday but as it's Saturday evening I thought I'd ask on here. I guess I have to wait until 48 hrs to shower now as well I've removed the dressing.
