I didn't have a lletz, just a couple of punch biopsies, but I definitely ended up with an infection after the procedure. I went to my GP and they didn't do any examination bar feeling around my belly. Then I got diagnosed with a UTI and was given a course of antibiotics -- no swab required!
That said, I'm feeling a bit better but still not 100%, and just started bleeding again, so I'm wondering if I've actually had two infections at once. Will be heading back to the Dr this or next week to get swabbed, so perhaps it's for the best to get it out the way first time?
I totally sympathise with not wanting to be prodded or poked anymore -- I put off the first GP appt for that reason! Not recommended, the infection hit me HARD after that!
Hope that helps and get well soon :) x
