Question
Small yellowish lump under the skin just above my kneecap. Surrounded by a huge red and purple bruising that seems to be spreading out. The lump has been there for about 3 days. The "bruising"started today. The lump doesn't hurt until I put some pressure on it. I also have a fever today.

Brief Answer:
start antibiotic

Detailed Answer:
Hello,
It appears like an abscess.
Although there should be pain in abscess, but fever suggests that there is pus in the body.
Start an oral antibiotic immediately.

Let me know the following things.
1. Is there a rise in temperature over the swelling, I mean does the lump feel much warmer than rest of your skin?
2. Do you have any difficulty in folding knee?

Please attach a photograph of the lesion.
This will help me in giving a closer diagnosis.
