Painful wart on the bottom of your foot and you cant really afford to go doctor for something as little this have tried duck tape but it comes off when walk how can get off?

Freezing the wart: Applying a topical freezing solution, such as over-the-counter Wart Remover, directly to the wart can cause it to freeze and eventually fall off. Follow the instructions on the product carefully and avoid applying it to healthy skin.

Salicylic acid treatment: Salicylic acid is a common ingredient in wart removers. Apply a salicylic acid patch or gel directly to the wart on a regular basis, as directed by the product instructions. This will help peel away the layers of the wart gradually.

Duct tape occlusion: While it sounds like you have tried duct tape already, ensuring that the tape is applied correctly and remains in place for an extended period can be effective. Cut a small piece of duct tape and cover the wart completely, making sure the edges of the tape are securely sealed. Leave the duct tape on for several days or until the wart falls off. If the tape starts to come off, apply a new piece.

Natural remedies: Some people find success with natural remedies like applying apple cider vinegar, tea tree oil, or castor oil directly to the wart. However, there is limited scientific evidence to support the effectiveness of these remedies.

It's important to note that while these self-treatment options may be affordable, they may not be as effective as professional treatments performed by a doctor. If your wart does not improve or becomes painful, it's best to consult a healthcare provider for proper evaluation and treatment.
