Is an anal rash after shaving cream or flea bites serious?

Question

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 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 disappear when I press on them, mostly on my lower legs and foot, and two on my arms, together with symptoms of a runny nose and sneezing only. And I accidentally discovered that my cat has many fleas, and I took her to the veterinarian.

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 healing slowly, and now I do not have sneezing or a runny nose anymore. But I did not tell them about the lesion on my buttocks.

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

Hope you are doing well.

After carefully reviewing your history and the images you shared (attachment hidden to protect the patient's identity), the lesions appear to be eczema or dermatitis, which likely developed after an insect bite reaction. Sometimes, when the skin reacts strongly to a bite and is scratched repeatedly, it can turn into inflamed, thickened patches of eczema.

From the images, multiple eczema patches are visible over your private area and legs. The likely trigger could be a flea or tick bite, possibly from a pet. Although the original bite seems to have healed, the area has developed dermatitis due to prior skin trauma and persistent irritation.

These lesions typically present with redness, thickened or plaque-like skin, persistent itching, a burning sensation, mild pain, and occasionally oozing or discharge from the affected area.

Eczema can also be associated with allergic tendencies such as bronchial asthma or allergic rhinitis (morning sneezing, runny nose, dust sensitivity, etc.).

I suggest the following treatment plan:

Mometasone and Fusidic acid cream (Momate F / Etasone F) should be applied in a very thin layer once daily at night on the affected areas only for two weeks. Since this is a strong medication, it should be used sparingly and only in small quantities. It helps reduce inflammation and redness while preventing secondary bacterial infection. If required, it may be continued in cycles of two weeks with a two-week break in between.
Tablet Cetirizine 10 mg should be taken once daily, one hour before bedtime, for two weeks. It helps reduce itching and inflammation associated with eczema. Since it may cause drowsiness, it is advisable to avoid driving or engaging in activities that require alertness after taking the tablet.
Aquaphor ointment should be applied twice daily for at least four weeks to maintain skin hydration and repair the barrier.
Capsule Omega-3 can be taken once daily after dinner for one month to support skin healing and hydration.
Tablet Ascorbic acid 500 mg can be taken after breakfast to promote healing and boost immunity. Avoid milk and very hot food/drinks 30 minutes before and after taking medications.
Ketoconazole 2 % cream is applied once daily in the morning for four weeks to prevent fungal infection.
Oilatum soap (liquid paraffin-based), use diluted with water while bathing. Apply to the affected areas, leave for two minutes, then rinse.
Clean the affected area once daily to reduce inflammation and prevent infection.

With proper care and regular application, these lesions usually improve well.

I hope this helps.

Hi,

Welcome back to icliniq.com.

I read your query and can understand your concern.

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 they 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.

I hope this helps.
