You are right it might be a deeper abrasion, it may be an infection as well...it may be contact lens
with corneal edema
I'm glad you have discontinued the contact lens. Discontinue till your cornea is healed. If you have an antibiotic drop handy please start hourly
See your ophthalmologist to rule out any other pathology. Accordingly she would add steroids
& tear substitutes, if required.Do not use steroids on your own.
