What Is The Treatment For Black Rash?

Hello, I was recently bitten by what I believe to be bedbugs and it's been about a week and a half now and the bites have dried up but now black rash spots are appearing on my chest, stomach, back and arms. It seems to be spreading on my face as well. I'm at such a loss and I'm very fearful

Dermatologist 's  Response
Hi
Welcome to Healthcare Magic Forum

Looks like you have developed a lesion of Vector dermatitis, also known as Paederus dermatitis..
Paederus dermatitis is a peculiar, irritant contact dermatitis characterized by a sudden onset of red lesions on exposed areas of the body.
The disease is provoked by an insect belonging to the genus Paederus.
You need to apply an antibiotic/steroid combination cream over the lesion twice a day.
Take oral antihistamine like levocetrizine once a day to decrease the swelling.

Do not use any moisturizer or oils till the time the lesion heals .
If the lesions continue to increase inspite of the above treatment, then you might have to see a dermatologist as in severe cases, short term courses of oral antibiotics or oral steroids may be required.

Hope it helps
Wishing you speedy recovery
