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.
