I woke up this morning to find a red spot near my knee. It is almost perfectly circular with a puncture mark in the center. It is a deep red with a deeper red outer ring. It has a spreading red "blush" around it and is painful. Anyone have a clue what this is? I am fair skinned and rarely outside with exposed legs. There is no history of cancer in my family either.

Hello, and thanks for your medical question on E Health Forum.

From the history and the description the possibility to know what exactly might have bitten you is diffcult without a physical examination. But it seems that the site is inflammed due to secondary bacterial infection.

Your pain might subside by regular application of ice packs and use of ibuprofen.

If symptoms worsen with onset of severe pain, change in color of the wound, etc seek immediate medical attention for medical treatment and antibiotics.

I hope this helps.
