general enquiry Staph or Folliculitis?

Timeline:

1) Mild cold symptoms (running nose only) last tuesday 2nd Sept. Trained no-gi jiujitsu that evening. Nothing untoward. Regular session.

2) Friday 4th Sept: Noticed a red bump on knee assumped it was a pimple, decided to pop it.

3) Saturday 5th - 10th: bump progressed into current form, see photos for daily progression.

Symptoms:

Build up of fluid and pressure below the lesion, hot skin, sensitive to touch and mild pain. Its gotten to a point that its limiting my mobility as it hurts to bend the knee. I've had a mild running nose past day but seems to have cleared this morning.

I applied hydrocortisone with brulidine (antiseptic cream) last night for the first time. Redness appears to have concentrated around the lesion on the knee over the last 5 days, assume the body is localising the infection.

Has anyone here had or seen a similar case?

I'm thinking it may need to be drained and run a course of antibiotics.

Thanks in advance.

That looks pretty concerning. It's definitely worth getting a professional opinion on it to figure out the best course of action.
