I have little red bumps on my back and my chest. they kind of look like flea bites but i'm not quite sure what they are. can somebody please help me?

See a dermatologist: Without being able to see these impossible to diagnose.

Agree w Dr Raff.: Flea bites may be clustered into 3 itchy bumps that bleed & blanch (turn white) when you press on them. They tend to be found at skin folds (breast or groin) & folds of joints (ankle, knee, elbow, axilla) as well as the legs. A rash may develop and swelling can occur as well as secondary infection from scratching. A skin biopsy is sometimes needed to make an accurate diagnosis.
