You are right..there is possibility of hand,foot and mouth disease.
It is a viral infection caused by coxsackie virus A 16.
It is mostly occuring in children.
There may be erythematous vesicular eruptions on hand and foot with mild itching and burning.
There may be fever.
Ulcers in mouth may occur.Antiviral acyclovir
tablets may be given in proper dose.Antipyretic
and antihistaminics may be given.Silver sulfadiazine
cream may be applied.
The disease is self limiting and may be aborted in 2 to 3 weeks.
However, it may recur.
I hope you got my answer.
