Hi about 6 months after my pain started in my leg and was dx with RSD and PN I started to have eye problems that got so severe I was crying from pain of the eyes. The pain also began to go to the ear where the pressure was so bad and like a horrible ear infection. During a year or so I went to 10 eye specialists, 50 eye apts,neurologist,mris etc there was nota cause other then blepheritis and dry eye but that does not cause the horrid pain that I experience. I saw Dr Stanton Hicks and from my experience he does not believe in rsd in the eyes cause he suggested another eye doctor and when I was talking about my eye pain he brushed it aside and the focus was on the legs only. I have heard others with rsd who have it in their eyes so though it may not be as common as in the limbs I do think it can be and is for myself and others. I hope the treatment I find for my legs will also help with the eyes. For others as well too. My ear pain I feel is connected or spread to the ear because my eye pain and about 6 months after it started it changed the type of pain and it began going to the ear. I have no idea if I am making any sense. Sorry I could not offer more help just that I am in a similar position. Hope your daughter feels better
