A few among 100 types of Human papillomavirus (HPV) cause common warts.
Most types of HPV are harmless whereas few types of HPV are likely to cause serious disease such as cancer of the cervix.
Warts are contagious and may spread from one part to other areas of your body. The virus can also spread if you touch something that has been touched by other person's wart, such as a towel or exercise equipment.
Breaks in your skin such as, a hangnail or a scrape could provide entry to the virus. Your fingertips and area around nails can also get infected if you have habit of biting your nails.
Not everyone who has or comes in contact with HPV is affected by warts.
4 Making a Diagnosis
Your primary care doctor may refer you to a dermatologist (a doctor who treats skin disorders) to make a diagnosis of common warts.
How to prepare yourself for the visit
Getting prepared for the visit can optimize the therapy and help make the visit more fruitful. List out all the symptoms.
Write down your key medical information. Write down the names of all your medications, vitamins or supplements. Ask a friend or a family member to accompany you during the visit.
Make a list of the questions to ask your doctor
Some typical questions can be:
What could cause these warts?
Can these warts recur even after treatment?
What are my treatment options and side effects of each options?
What tests are needed in case these growths aren't warts?
What can I do to prevent warts?
What your doctor wants to know
A clear talk with your doctor can optimize the therapy and improve the outcomes. Prepare yourself to answer some essential questions from your doctor. Your doctor might ask you typical questions like:
When did the warts become apparent?
Do you have a personal history of warts?
Do the warts annoy or embarrass you?
What treatments did you use for warts in the past? If so, how long did you use them and did they work?
Diagnosis of common warts include following tests:
Your doctor may examine the wart physically
The top layer of wart is shaved off to see if there are tiny black dots which are present on most of the warts
A small portion of wart may be shaved (biopsy) for laboratory analysis to check if it is any other kind of skin growths.
Most common warts need no treatment. Common warts disappear on their own though it may take few years and new ones may develop near the older ones.
Few people choose to treat their warts since they find it troublesome and annoying. Some may opt for treatment because the warts don’t look good or keep on spreading.
The treatment approach depends on the location of your warts, symptoms and preferences. Treatment is aimed to remove the warts, activate your immune system to fight against the virus, or both.
Warts may spread or return despite being treated. It may take weeks or months to treat your wart.
Doctor usually treats your warts with least painful treatment option, especially in kids.
Medications to peel off the wart
Salicylic acid peels off the layers of a wart a little bit at a time. Salicylic acid when combined with freezing has proved to be more effective treatment.
Cryotherapy uses liquid nitrogen to destroy warts. You may need the treatment for a couple of times. Cryotherapy might activate your immune system as well.
Side effects of cryotherapy are pain, blistering and discoloration of treated skin.
Bichloroacetic or trichloroacetic acid may be chosen if salicylic acid or cryotherapy fails to treat your wart. The surface of the wart is scraped off followed by application of the acid.
You may need to be treated every week. It causes burning and stinging sensation.
In pulsed-dye laser treatment, the tiny blood vessels that are present in warts are burnt (cauterized). This leads to death of the tissue, and the wart eventually falls off. Side effects include pain and scarring.
With the following measures you can prevent common warts:
Don't touch the warts.
Avoiding picking warts to prevent transmission of the virus.
Avoid using the same emery board, pumice stone or nail clipper for your warts and healthy skin.
Don't bite your fingernails. Virus can spread to broken skin due to biting of skin around the fingernails.
Groom with care. Use emery board that can be disposed. Don't brush, clip or shave around the warts. Use an electric razor while shaving.
Do not forget to wash your hands carefully after touching your warts or surfaces, such as shared exercise equipment.
7 Alternative and Homeopathic Remedies

Freezing: Over-the-counter liquid nitrogen is found as liquid or spray preparations.
