Question: Blood rash under skin

 JenH - Sat Dec 23, 2006 2:18 pm

I'm a 26 yr old female. About two weeks ago I woke up with an underneath the skin blood rash spreading from my ankle up to my knee on both legs. Since then I have developed more patches on my thighs, upper stomach area and arms. They are small red specks in a variety of redness and size. Does this sound serious?

User avatar Hello,

Is this your first time to experience this rash? Have you been on drugs recently or this happened following the intake of certain food or have you got an infection recently?

This sounds like an allergic reaction (hives -urticaria) a type of skin reaction to an allergen, medicine or infection and are common in individuals who are very nervous.
If these lesions are irregular, raised or flat red that appeared after eating certain food, intake of certain drinks, or taking a medicine then it could be the case .

Allergic skin reactions to drug may start within two weeks of taking a new medication, (usually the drug drug was taken before)
Some viral infections cause similar rash.

Direct clinical examination is essential.
Best regards.
