Plantar Warts: Treatment Progress and What to Expect - Dermatology

More Info

Plantar warts, also known as verrucae plantaris, are benign growths caused by the human papillomavirus (HPV) that typically develop on the soles of the feet. They can be quite uncomfortable and may cause pain, especially when walking or standing. The treatment for plantar warts often involves methods aimed at destroying the wart tissue and stimulating the immune system to fight off the virus. One common treatment is cryotherapy, which involves freezing the wart with liquid nitrogen.

From your description, it seems that you have been undergoing cryotherapy for over a month, and you have noticed a hard callus forming, which eventually fell off, leaving a hole. This progression is not uncommon in the treatment of plantar warts. The hard skin that forms is often a protective response from the body as it attempts to heal the area. When the callus falls off, it can reveal the underlying tissue, which may appear as a small pit or hole. This is generally a normal part of the healing process.

However, it is essential to monitor the area closely. If the hole is deepening, becoming painful, or showing signs of infection (such as increased redness, swelling, or discharge), it is crucial to consult your healthcare provider. They can assess whether the wart is still present and if further treatment is necessary.

Continuing cryotherapy may be recommended if the wart is still visible or if there are signs that the virus is still active. The goal of cryotherapy is to destroy the wart tissue, and sometimes multiple sessions are required to achieve complete resolution. After each treatment, it is normal for the area to undergo changes, including the formation of callus or scabbing, as the body heals.

In addition to cryotherapy, other treatment options for plantar warts include topical treatments containing salicylic acid, which helps to peel away the wart gradually, and laser therapy, which can be effective for stubborn warts. In some cases, immunotherapy may be considered, where the immune system is stimulated to fight off the virus.

It is also important to take preventive measures to avoid re-infection or the spread of warts. This includes keeping your feet clean and dry, avoiding walking barefoot in public places, and not sharing personal items like shoes or towels.

In summary, the hole you are observing after the callus has fallen off is likely a normal part of the healing process following cryotherapy for plantar warts. However, it is essential to keep an eye on it and consult your healthcare provider for further evaluation and guidance on whether to continue with cryotherapy or consider alternative treatments. Regular follow-ups are crucial to ensure that the wart is being effectively treated and to prevent any complications.
