You could try colloidal silver. Look it up

my left eye hurts.its not pink. it does not discharge a lot its tender sore pain seems not in front side of head by left eye get little jabs of pain on side by the eye been this way for 6 weeks

A visit to your eye doctor would be in order since this hs been going on for 6 weeks, it does not appear it will go away on it's own...

You might want to consider the fact that it might be a Parasite, most medical persons overlook that fact and it goes on too long and is untreatable by that time.
Try suggesting to a doctor or whoever you choose to visit that it could be possibly a parasite.

Dont think it couldnt happen to you, cause it could happen to anyone. And it would probably be the best explanation for the "biting" feeling..
nip it in the butt as soon as possible, dont wait.
