A chalazion started forming 3 weeks ago on my upper eyelid. 5 days ago, it came to a head and popped (pus and blood came out). My eyelid no longer hurts, but there's still a bump on it. I was using an antibiotic that goes directly in my eye (Maxitrol) as of a few days ago; I stopped b/c the ophthalmologist said to only use it for 10 days. I'm still using a heated eye mask about 4 times a day. Does it look like I need to get a steroid injection or surgery? Or should I continue to wait for now?
