Patient's Query

Hello doctor,

I have had a rash around my anus for ten days. It started around ten days ago. And one week before that, I shaved my buttocks using a cream for hair removal. It started as an itchy burning, a single small lesion that grew up and became more. Sometimes it is painful, especially when I walk, but now it is not painful anymore. Also, at the same time, there are small itchy lesions that look like insect bites that appeared on my skin that disappears when I press on it, mostly on my lower legs and foot, and two on my arms, together with symptoms of runny nose and sneezing only. And I accidentally discovered that my cat has many fleas, and I took her to the veterinary doctor. And I went to a dermatologist last week only for the insect bites, and they gave me the antihistamine Xyzal, and the insect bites are being healed slowly, and now I do not have sneezing or runny nose anymore. But I did not tell them about the lesion on my buttocks. So can you help me, please?

Hello,

Welcome to icliniq.com.

Hope you are doing well.

Having gone through the history and the images provided from your end (attachment hidden to protect patient's identity), they are eczema, or dermatitis lesions formed post insect bite reaction. Eczema occurs due to long-term insect bite reactions and due to incessant scratching. Multiple lesions of eczema are visible along your private as well as leg areas, as per the image. The most probable cause might be a flea or tick bite from your pet's scar. In the chronological order of images provided, the insect bite reaction lesion, although it has healed but has turned into dermatitis or inflamed skin where there was a previous trauma. They usually present as redness, thick skin or plaque, itching, sometimes oozing secretions, pain, burning sensation, and discomfort. They are usually reduced with treatment. Eczema also may be accompanied by underlying allergic conditions like bronchial asthma and allergic rhinitis (sneezing and running nose, especially during mornings, on exposure to dust or cold, etc.).

I suggest:

1. Mometasone and Fusidic acid cream (Momate F or Etasone F) to be used once daily at night in a very thin layer in a small quantity on the affected areas only for two weeks. This is a strong medication and, therefore, may be used in small quantities and may be continued for two weeks each time with a two-week break in between. They help with reducing inflammation and redness and preventing secondary bacterial infection. The brand with the combination mentioned above may be purchased, or the brand name mentioned along with the same may also be available.

2. Tablet Cetirizine 10 mg one hour before going to sleep at night for two weeks. They help with reducing itching and inflammation. It is advised not to drive or go out after consuming the tablet at night as it may be sedative.

3. Aquaphor (Sodium chloride and water) ointment is to be applied on the affected area two times a day for at least four weeks. They may be available online easily as well.

4. Capsule Omega 3 once daily at night after food for one month to promote hydration.

5. Tablet Ascorbic acid 500 mg to be taken after breakfast for faster healing of the current lesions. They help in strengthening immunity as well. I would like to advise you to kindly avoid milk and extremely hot food and drinks 30 minutes before and 30 minutes after the intake of the medication.

6. Ketoconazole two percent cream in the morning on the affected areas only for four weeks. This may be helpful in preventing fungal infections.

7. Oilatum (liquid Paraffin and water) soap for bathing. Mix the soap with water and apply the water on the affected area, leave for two minutes and wash off.

8. Lukewarm salt water may also be used to wash the affected area once daily. It is very helpful in reducing inflammation and preventing secondary infection.

Hope the details provided above were informative and did provide clarity.

Kindly revert back in case of further queries, and I would be glad to help.

Hope I could be of help.

Stay happy, healthy, and safe.

Get well soon. Take care.

Kind regards.

Patient's Query

Hi doctor,

Thanks for the response.

The insect bite lesions on my legs do not look like these in my private. And even though I always rub them but they never grow up or turn into eczema or dermatitis. And as I know, insect bites usually tend to locate around the areas that have more bone under the skin, such as legs. So, could these lesions in the buttocks be something else? Please help, and thank you.

Hello doctor.

Welcome back to icliniq.com.

The lesions may be infected secondarily with fungal infection and may reduce in intensity with the medications included previously. You may use the medications in your private area as well. Do not worry. They are not dangerous but may be symptomatically bothersome.

Kindly follow the medications. It will be helpful in reducing their intensity. Due to their location and severity, it may take months to reduce but will eventually fade. Also, kindly make sure to avoid stagnation of moisture and sweat in the areas and make sure to air the areas well and towel dry them following a bath.

Hope the information was helpful.

Take care and get well soon.

Kind regards.

Same symptoms don't mean you have the same problem. Consult a doctor now!
