Can shower gel be used for bathing with papular urticaria?
"When hives appear, it is best not to use body wash during bathing, as many body washes can irritate the skin, exacerbating the condition and likely causing itching. Scratching can lead to hyperpigmentation. Therefore, when hives occur, it is advisable to treat with anti-allergy medications under the guidance of a doctor. You can take oral medications such as loratadine tablets, levocetirizine dihydrochloride tablets, or desloratadine dispersible tablets. Treatment with traditional Chinese medicine is also an option. This can be combined with proprietary Chinese medicines such as Xiaofeng Stop Itch Granules, Runzao Stop Itch Capsules, and Skin Disease Blood Poison Pills. Topically, proprietary Chinese medicine ointments such as Dampness-Removing Itch-Relief Ointment or Binghuang Fule Ointment can be used. Dietary adjustments should also be made to avoid spicy and irritating foods."
What are the symptoms of syphilis in women?
In the early stages of syphilis in women, a hard chancre appears, often accompanied by swollen inguinal lymph nodes. These nodes are about the size of a finger, relatively hard, non-fusing, painless, and without tenderness; their surfaces exhibit no redness, swelling, or signs of inflammation such as fever. The lymph fluid from a puncture will contain Treponema pallidum (the syphilis bacterium). During the early stage of syphilis, the appearance of a hard chancre significantly increases the positivity rate for syphilis. If the hard chancre is not treated timely, it generally disappears naturally within three to four weeks, after which it enters the latent phase of secondary syphilis. The second stage of syphilis is typically characterized by patches of varying-sized erythemas on the trunk and copper-red, symmetrical maculopapular rashes on the palms and soles. Upon detection of syphilis, prompt and thorough treatment is essential.
Are cracked heels with calluses and blisters athlete's foot?
Heel cracking, calluses, and blisters appeared, and it is considered likely to be athlete's foot, which is mainly caused by fungal infection. Athlete's foot has several types, one of which is called the hyperkeratotic dry type, mainly characterized by dry, cracked heels, and is also accompanied by itching. Therefore, if there is heel cracking, calluses, and blistering, it is advisable to visit the dermatology department of a formal hospital promptly. You can have a fungal microscopy test and if it is confirmed to be a fungal infection causing the athlete's foot, treatment with antifungal drugs can be carried out. You may choose nitrate oxiconazole ointment or luliconazole ointment, as well as special terbinafine cream for treatment. If the symptoms are severe, oral antifungal medication should also be used in combination.
How to identify if it is syphilis rash?
To determine if it is syphilis rash, one can usually judge by the symptoms. The appearance of syphilis rash lacks obvious distinctive features, typically manifesting as red macules and papules all over the body, some might be patches. There are nodules on the skin, pustules, and some might also develop ulcers. After the appearance of syphilis rash, it generally does not cause intense itching and manifests symmetrical copper-red papules in the palms and soles of the feet, which is typically seen in secondary syphilis. If there has been unprotected sexual activity and these rashes appear on the limbs and trunk, it is necessary to visit a dermatology department in a standard hospital for specific examination. Many skin diseases have similar symptoms, and it is usually difficult to diagnose based solely on the appearance of the lesions.
How to treat solar dermatitis?
For photodermatitis, treatment mainly involves the use of antiallergic medications, and topical application of corticosteroid drugs such as hydrocortisone butyrate cream or fluticasone propionate ointment. If blisters and obvious exudation occur, boric acid solution or saline solution can also be used for wet compresses to reduce exudation. Oral antihistamine medications, such as chlorpheniramine maleate tablets or ketotifen fumarate tablets, can also be used in conjunction with the treatment of photodermatitis, which primarily involves the use of antiallergic and anti-itch medications. Photodermatitis mainly occurs due to excessive exposure to ultraviolet rays, therefore, it is essential to avoid direct sunlight, take sun protection measures when going out, and regularly exercise to boost the body's immune system, which can effectively improve an allergic constitution.
How to treat itchy scalp and hair loss?
Itchy scalp and hair loss are commonly caused by seborrheic dermatitis. Initially, treatment should aim to control the symptoms of seborrheic dermatitis. Under the guidance of a doctor, oral treatments such as ebastine tablets, ipristine capsules, or levocetirizine hydrochloride tablets may be used. For topical treatment, halcinonide solution can be applied. If there is an excess of oil and dandruff, selenium sulfide can be used for shampooing. By controlling seborrheic dermatitis, significant improvement can be seen in hair loss and scalp itchiness. Another scenario involves scalp itchiness accompanied by hair loss, which may be caused by a fungal infection leading to tinea capitis. Under the guidance of a doctor, ketoconazole shampoo can be used for washing the hair, and terbinafine hydrochloride spray can be applied locally for treatment.
Is it normal for papular urticaria to be neither painful nor itchy?
Papular urticaria is neither painful nor itchy and is also considered normal. The occurrence of papular urticaria, which is neither painful nor itchy, is related to the consumption of some anti-allergic drugs, and also due to a mild allergic reaction to external factors. It also has something to do with individual physical constitution. Papular urticaria generally results from allergic reactions caused by bites from mites, fleas, mosquitoes, and other such pests. Most people will experience obvious itching, and some may also feel pain in addition to the itching. For cases of papular urticaria, patients can apply anti-allergic medications under the guidance of a doctor. Common choices include desonide ointment or fluticasone propionate ointment for itching, often in combination with oral antihistamines such as cetirizine tablets.

Can I apply corn plaster if the corn has burst?
If a corn has broken open, you should not continue to apply corn plaster to it, as the plaster is somewhat corrosive. Since the skin of the corn has already been damaged, you should not use this medicated plaster until the skin has healed. Corns typically develop on the skin due to prolonged friction and pressure on the foot skin. Wearing ill-fitting shoes for a long period, or having deformed feet or toes, can also lead to the development of corns. If you have a corn, you can apply corn plaster locally, or visit a formal hospital to receive treatments such as cryotherapy with liquid nitrogen or using a carbon dioxide laser. If the corn has broken open, pay attention to the cleanliness and hygiene of the foot to prevent further infection. You can apply iodine locally for disinfection.
How to deal with heat rash that doesn't itch?
If prickle heat appears without itching, you can apply some Calamine Lotion locally. If the symptoms are not severe, you may not need any special treatment. Wear loose and breathable clothing, avoid excessive sweating, keep indoor air circulating, avoid direct sunlight, refrain from intense physical activities, drink plenty of water, and using foods that clear heat, cool the blood, and detoxify can also lead to significant improvement. Prickle heat usually occurs due to high temperatures, high humidity, and excessive sweating. Whether prickle heat causes itching varies from person to person; some people feel very itchy, whereas others do not show any symptoms, such as when white heat rash occurs, usually there are no noticeable symptoms. If prickle heat is accompanied by itching, treatment under the guidance of a doctor with antihistamine drugs may be necessary.
Can tinea capitis heal by itself?
Some cases of tinea capitis can heal on their own. Clinically, tinea capitis is divided into white piedra, black dot tinea, yellow piedra, and kerion. White piedra can heal on its own, usually after puberty. Post-puberty, Malassezia may colonize the scalp and secrete free fatty acids, which have a certain killing effect on white piedra, so it may resolve without treatment. However, if the tinea capitis is yellow piedra, black dot tinea, or kerion, these types cannot heal on their own and may cause permanent hair loss. Therefore, it is crucial to treat these types promptly with antifungal medications under a doctor's guidance and pay attention to personal hygiene.
