After my last colp I felt niggly like when I get cystitis so I have been drinking lots of cranberry juice and water to try and keep things flushed thru. TMI but this week 2 weeks post Lletz I then felt itchy so slapped on the thrush cream and that seems to be doing the trick.
You could have a uti I know if I have "ahem" rough sex :$ I sometimes get cystitis so a colp with the whole speculum/ cranking you open could well bring on a UTI if u are that way inclined. So start drinking lots of water/ cranberry juice to flush things through and then maybe call the colposcopy nurses to see if you can take cystitis meds.
Hope your stinging subsides soon
