Bulge - where?
If the bulge is on your eyeball you need immediate evaluation by your ophthalmologist especially if it is affecting the vision
or making the eye
Most bulges of this type are in the substance of the lid, a product of what probably began as a stye. You could try using heat on it if that is the case. A very warm, not hot, washcloth held on for 4 minutes five times per day.
