I recently had a problem with my contact lenses specifically my left eye. I put the lens in as usual in the morning, but by 11 am it hurt so much I had to remove it. My eye became very bloodshot, and had a lot of itching and burning but no discharge. I have continued to experience a sensation similar to having something in my eye, and when I used the magnifying glass to look at my eyeball, I noticed a small white bump directly on the eyeball. I have been trying not to rub my eyes, but know I have done so inadvertently. Is this bump something to be concerned about, and what might be the reasons for its appearance? I have never experienced this before. Thank you for any information you might have.
