Foot Wart Verruca Pain
A foot wart, verruca or plantar wart is no different than a wart on any other part of the body. These warts eventually go away by themselves, but they are potentially contagious and could stay around for a couple years; treatment is usually recommended to decrease the length of pain, the duration of pain and to decrease the chance of transferring it to other parts of the body.
Cause of a Foot Wart or Verruca
- HPV (Human Papilloma Virus) is the cause of warts.
- The virus can stay alive for many weeks without a host ,especially in the shower!
- The wart enters through microscopic cracks in the skin of the foot or the fingers.
- If a cluster of warts forms, it is called a Mosaic wart which can create extremely large surface areas.
- It is completely normal to get a wart – most warts occur in 12-16 year old children, but are very rare in older age.
Symptoms of a Foot Wart or Verruca
- Not usually painful although may be tender when pressed, especially from the sides.
- The verruca may feel like a small stone under the foot.
- It looks different from a callus because of little red pin like dots- a callus looks like normal but thicker skin.
- There is usually a callus that forms around the wart.
Diagnosis of a Foot Wart or Verruca
- Verrucas vary in size from a 1mm to over 1 cm and may vary in shape too.
- The surface of the verruca is usually covered with small black dots (blood vessels).
- They are usually surrounded by hard skin.
- There is usually nothing ever really tricky about diagnosing a wart.
- If the wart is really large then it is a more resistant mosaic wart that needs more attention.
Prevention of a Foot Wart or Verruca
- Warts and verrucas are very common and nothing to get worked up about (especially ages 12-16 years old), although they should be treated as they are mildly contagious.
- They are only passed on via direct skin to skin contact and can be passed to other people or to other areas of your body (although this is more common when warts appear on the fingers).
- There is a higher risk of passing a verruca if the skin is damaged or wet.
- Swimming pools are common infection area for verrucas.
- To avoid passing on a verruca, make sure it is covered when you go swimming (either buy a waterproof plaster, duct tape or special verruca sock), wear flip flops when walking barefoot and in the shower and don’t share towels.
Home Treatment of a Foot Wart or Verruca
There are many available treatment methods without a clear winner, because even doing nothing after a little while will make the wart go away! Studies show that you can make them go away a little bit faster and some of the best treatments achieve 70-90% cure rates within a couple weeks. If you have a mosaic wart then the chemical treatment approaches are recommended.
1st Line Therapy of a Foot Wart or Verruca
– Duct Tape is my favorite method to try first!
This is a controversial treatment method, some scientific literature states that it works great and it can resolve the majority of warts over a couple weeks, but then other papers say it does not work at all. I say whats the harm in trying it! This method has always worked for me, and if it didn’t work in the future- you can always move on to the other treatments!
-Theoretically this should work, there will be some pain! Compare this to the duct tape method which is slower, safer and has no pain.
-This medication is known as a keratolytic agent which works by “loosening” the surface of the wart. Use this medication as directed by your pharmacist or your podiatrist.
2nd Line Therapy
– All of these have shown to be effective, but it is unclear which is the best (which means none of them are clearly better than any other). Canthardin and Cryosurgery are the most commonly used in podiatrist offices.
This is a more painful but more effective agent than salicylic avid. It causes a blister to form within a day or so of application to your blister.
The wart is touched by a liquid nitrogen swab. This freezes the cells of the wart destroying the tissue and stimulating new tissue to come up behind it. This sounds a lot more intense then it really is!
This is a fairly new treatment that involves injecting something (any dead foreign particles that are not dangerous) that irritate your immune system to attack this area. As a “coincidence” the immune system cells wipe out the HPV virus that is causing the wart.
3rd Line Therapy
– The most common method is to cut the wart out and then use electricity to singe the underlying tissue under anesthesia.
– If the wart is extremely resistant consult a podiatrist about invasive treatment. These treatments are usually reserved for warts that have survived the first and second lines of treatment.
–Surgery– This can be done inside the office if the foot is not massive, but if it is a large mosaic wart- then the OR is usually necessary. The foot is numbed with anesthetic, then then the wart is simply cut out down to bleeding. The tissue is then heated to close it up; don’t worry, you won’t see whats happening! The wart can be considered as good as gone at this point and while there will be a scar, it should not be something that ever bothers you.
-Electrocautery– this is combined with surgery to burn the area where the wart used to be.
-Laser Surgery- It is a choice, but from what I have heard and seen it is more expensive than practical.
