Something went into my left eye 3 weeks ago. It came out but there's constant feeling that something is still in my eye and when I try to look, there's not anything. It also causes headache on my left side. And I feel a little pressure on my left eye lid. After 2 weeks, same feeling is in my right eye. But I don't feel pressure on eyelid and headache on my right side. But feeling of something in my right eye is there. Water hurts in my right eye also now. Please help.
