How long after freezing the wart can I get wet?

The human body is very strange, and sometimes diseases that occur can make people feel helpless. Many people will have some lump-like things growing on their bodies. This is a disease, and people in the folks call these things warts. If a young person gets a wart, it will greatly affect his or her image and can only be treated by freezing. How long after freezing the wart can you get wet?

1. Can common warts come into contact with water after being frozen?

It can come into contact with water after being frozen, but if you are worried, wait 20 hours and it will definitely be able to come into contact with water. Only during laser treatment it cannot come into contact with water for several days.

Cryotherapy is a way to treat warts, but because it will cause scars and children's tolerance is not as strong as adults, cryotherapy is not the best treatment for children. It is best to use drug treatment.

The main active ingredient of cryotherapy is liquid nitrogen. The principle of cryotherapy for warts is to release liquid nitrogen at a low temperature of -190 degrees to produce instant cold air, which then freezes the warts growing on the hands and other parts of the body, making the wart cells dehydrated. Coupled with the high concentration of electrolytes, the wart cells will die, thereby effectively inhibiting the growth and proliferation of warts, killing viruses, and achieving a therapeutic effect. Cryotherapy is only suitable for the treatment of warts with small lesions and a small number.

Warts are caused by human papillomavirus (HPV) infection and can be transmitted through direct or indirect contact. Trauma or skin damage is also an important factor for HPV infection. The course of warts has an important relationship with the body's immunity. The mechanism by which warts persist for a long time in relatively healthy people is still unclear, but it may be related to local or systemic immune dysfunction or the development of immune tolerance.

Treatment of common warts

1. Systemic treatment

( 1) Traditional Chinese medicine, such as Pinggan Huoxue prescription, Zhiyou decoction, Purslane mixture, Isatis root injection, Bupleurum injection, etc.

(2) For multiple and intractable warts, interferon can be combined with systemic or local injection of interferon. The efficacy of interferon alone is uncertain.

2. Topical medication

Since most warts disappear on their own within 1 to 2 years after onset, and even with deep destructive treatments, one-third of warts will still recur, the efficacy of various local treatments for warts should be evaluated with caution, and some methods that can cause permanent scars should not be used.

(1) Fluorouracil (5-FU) has a certain therapeutic effect. Possible adverse reactions include local pain, chapped skin, edema, allergic reaction, tearing, pigmentation and suppuration.

(2) Bleomycin is injected intralesionally once a week. Warts usually fall off after 2 to 3 injections, with few side effects.

(3) 0.7% cantharidin is added to equal amounts of collodion and acetone solution and applied externally to treat periungual warts. Apply once every other day and it has a certain effect.

(4) 0.1% to 0.3% retinoic acid alcohol solution is applied topically 1 to 2 times a day. Side effects include mild local burning sensation, redness, swelling, desquamation, and pigmentation.

(5) 3% phthalamide ointment or 3% phthalamide dimethyl sulfoxide lotion.

(6) 0.5% podophyllotoxin twice a day for 3 consecutive days. If tolerated, it can be used for 4 to 5 days. If the warts have not fallen off, you can continue the treatment every other week.

(7) Imiquimod 5% cream can be used for occlusive treatment of common warts or in combination with salicylic acid.

(8) Topical application of 1% cidofovir gel or intralesional injection of 2.5 mg/ml is effective for various warts.

3. Photodynamic therapy

Systemic or topical use of the photosensitizer aminolevulinic acid or aminolevulinic acid (ALA) can treat some common warts by inducing local cell death after light exposure.

4. Physical therapy

Cryotherapy, electrocautery, laser therapy, and infrared coagulation therapy are suitable for a small number of common warts.

5. Recurrence is common after surgical resection.
