Hi,
How is your husband? The skin lesion can be due to irritation, allergic reaction, skin conditions such as dermatitis, eczema, hives and other medical issues like anemia, liver and kidney conditions. It is important that direct clinical examination and further diagnostics be done to determine the underlying cause. Culture of the discharge must be repeated if the first sample was misplaced. He may also benefit from a referral to a dermatologist or skin specialist. Treatment will depend on the underlying cause. Keep the area clean and dry and tell him to avoid scratching to prevent secondary bacterial infection. Take care and do keep us posted.
Hello
Eczema - My four year old's eczema seems to always bother him more so at night. He'll wake up in the middle of the night screaming and intensly scratching himself.
Shingles - I don't know too much about it, but it does sound familiar.
Sorry I couldn't be much more help!
