[|Human|] It appears my grandson may have an insect bite on his thigh.  It is a small raised bump but the concern is the red line moving up from the bump.  He is not feverish, nor does he feel sick.  This incident occured about 4 hours ago.  May I allow him to soak in a bath of Epsom salts?  I have marked the area so that I may see if it gets any bigger...
[|AI|]  Hi Welcome to Chat Doctor Forum Looks like your grandson has developed a lesion of Vector dermatitis.also known as Panders dermatitis. Panders 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 Panders. You need to apply an antibiotic/steroid combination cream over the lesion (something like flutist, Unibet) twice a day. Take oral antihistamine like levocetrizine once a day to decrease the swelling (Dosage according to age of the patient) Do not use any moisturizer or oil over the lesion Do not cover the affected hardware cotton clothes Hope it helps To wish your grandson speedy recovery Chat Doctor.
