I have bed bug bites in my ears nose and all over my body is this serious and if so what could happen to me?

its not seirous; even though they itch like hell and take a few weeks to go away; call a bed bug specialist rite away to get your house sprayed . theres no way to get rid of them they have to gradually go away on there own . bed bugs are a big problem and theres no way to get rid of them w.o specialist . its expensive but worth it .
