Suggest Treatment For Pimple-like Nodule On Eyebrow

I noticed a pimple-like nodule on my left eyebrow line and a little scalyness on the left eyelid yesterday. Nodule is sore, eyelid burned. Today, nodule is smaller, but more sore and left eyelid is swollen and edematous, painful. I am a contact lens wearer, but elected to not place them in today. I am 42yrs old, 5 7 and 165lbs. I have a medical hx of allergies, asthma, and nasal polyps. Today, I treated my eye symptoms with a triple antibiotic ointment. Perhaps relevant to this scenario was a visit to a department store make-up counter where some cosmetic techniques were demonstrated on me, however, the person used all single-use devices and the containers were clean.
