a stye can cause inflammation and inflammation can cause edema/swelling -- one that will self-resolve over time. another possibility would be a secondary infection (bacterial) that may require antibiotics. this cannot be determined unless you have a hands-on examination by your medical provider.
why does a stye cause the part under my eye to be so puffy? . about 6 days ago i woke up with the under part of my eye puffy. after looking into my bottom eyelid i discovered a small white bump. we've been treating it with warm compresses several times a day & washing my face and eye lid with baby shampoo. the white spot on my eyelid seems to be getting better but the puffiness under my eye is not (it's where bags would be but it's only on the side with the stye). why is it so puffy do i need to go to the doctor for an antibiotic?
