My body is infested with fleas......in and out. My sinuses, my intestines, stomach,skin,ears,hair,face....everywhere. so is my house. We r also infested with rats. For 2 years I have tried to convince my husband. He refused to acknowledge the fleas or rat

I feel I need a Dr, what kind. Dermatologist treated for exema and hives. Laughed and dismissed the idea that fleas could be the reason. What kind of dr do I need. My husband refused to understand the microscopic size when they enter my body. This life cycle continually repeats itself. Never ends. I see them everywhere in my home. I see them in food, my fridge. I even see them in butter......toilet, counter tops, everywhere food is pretty prepared. please help me.
