I have severe dry eyes but also severe eye pain. I have been to 10 eye specialists about 50 apts,neurologists for mris,rheumatologist,allergist etc. The cause of why I am in crying pain at times they don't know and why it may be rsd in the eyes.
Now for some certain meds can cause dry eye. Do you have pain too? Do you wear contacts? Do you have any eye issues like blepheritis? I do and which I think caused the dry eye. I use preservative free eye drops.
