Patient :Around 3-4 months ago, a wart grew on the bottom of my foot and left it untreated for around 1 month. I decided to get it removed at the doctors and had the callus scraped and wart frozen every week for about a month. After we didn't see much change, we switched to using Cantharidin for about 2 weeks and worked great. The wart fell off and I stopped going to the doctors but now after about 2 weeks, another wart grew right above the old one and my "removed" wart is now swelling back up again. It also looks like there are things like air bubbles(?) in the wart. I have been using salicylic acid (Compound W, Clear Away) but it doesn't seem to be working and won't stay on properly due to the warts awkward placement. It's very flat but the area around it is very itchy and painful. I'm afraid that the warts will spread and I can't find any case where anyone has had many bubbles inside their wart... Can you please tell me what I should do?
