Hello,
I cannot confirm anything without examination but it can be due to fungal infection, eczema or dermatitis skin. Since the lesion is moist so fungal infection can be a possibility and for ruling it out, you need to get a KOH examination of the skin scrapings done. If fungal infection is proved, then topical and oral antifungals may be needed. Fungal infections are contagious but dermatitis and eczema are not.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
I read somewhere about the same symptoms I've got and it was the same as pruritus or the itch-scratch-rash-itch cycle. I've also retrieved some measures to help heal the wounds or cuts. Here is it:
Do’s:
• Bathe with lukewarm water
• Lubricate skin frequently with rich moisturizers like Aquaphor or Crisco vegetable shortening
• Use a soapless cleanser like Eucerin Gentle Cleanser
• Maintain a comfortable room temperature
• Keep fingernails short and clean
• Wear light, smooth, nonbinding cotton clothing
Don’t:
• Wear rough, scratchy clothes or woolens
• Bathe too often with hot water and soap
• Use harsh skin cleansing products or soaps
• Use fragrances lotions or body washes
