Can a gential wart rapidly change shape, size, color? flattened out completely then raise again every few days as a reaction to tca acid treatment?

Wart treatment: This often occurs during treatment of warts. Expect increased inflammation (e.g. redness, soreness, enlargement) for a couple of days after each TCA treatment. But the overall trend should be shrinking and drying up. If that doesn't seem to be happening after 2-3 applications, ask your doctor about alternative treatments. Most treatments work about 70% of the time, and change is often necessary.
