I already have some of the symptoms that can be caused by Restatsis. If it is going to do this, why should I take it. My eyes already burn and sting EVERY time I put eye drops in, which is 5-6 times per day. The ointment, Racitracin Zinc, does not keep the eyes from burning and stinging. The eyeballs feel as though they have been blistered, which I know they have not.
