Yes, I have had many lesions that left scarring that actually closed my vulva to my urethra, thus the need for laser surgery to evaporate the scars so urination was free. The burning when urine hits those lesions can be excruciating, and we’ve all experienced it. I recommend placing ozonated coconut oil, emu oil, or even Aquaphor over the lesions before you urinate to keep burning away.
Also a frozen bottle of water against your vulva for several minutes provides great temporary relief from lesions. I usually do that lying in bed.
Hugs to you.
