It seems that you may be having either irritant contact dermatitis
or insect toxic dermatitis.
There may be some irritant or some insect, which may be responsible.
Anyway, the treatment is same.
Take a short course of steroids
in tappering dose.
You take antibiotics to preve nt se condary infection.
I think, you may be benefitted.
I hope you got my a nsw er.
