Patient discussion about visualization

Q. Can visual aura alone be migraine? I'm 21 years old girl, and for the last six years, about once a week, when I wake up from night sleep all I see in my left eye is a very bright light. After some time my vision returns. In the last few weeks it became more frequent and also starts to happen in the other eye. I consulted my doctor and she told me it's not an important thing, and that it's probably a specific type of migraine. However, I don't have any pain at all. Does anyone else have this? Is it possible for migraine to occur only with aura, without any pain?

A. Hi,

I'm sorry to hear about your problem. Whatever your doctor told you, you should know that if it bothers you, it IS an "important thing". I also suffer from similiar thing (only visual disturbances after I wake up, without any pain), and when my doctor prescribed me meds they went away. You should consult your doctor again and ask him for a solution for this thing.

Q. What are the visual distinctions between thermal burns and frostbite? Is it possible to definitively distinguish the two from each other in all cases, or do they present identically in many cases? In other words, are frostbite injuries-for all intents and purposes, actual burns and if they are not, in what ways do they differ?

A. Early frostbite and minor burns may resemble one another visually (by whitened, blanched looking skin, and blister formation). However, last stage frostbite and thermal (heat) burns are very different.
In late stage frostbite, the ice crystals in the cells melt and the ruptured cells pour out their contents, then blisters may form. Since the affected area has basically lost circulation, gangrene sets in rather quickly and the tissue turns black and dry.
Deep (full thickness) heat related burns are surrounded by areas of erythema (reddened skin) and skin with less degrees of burning. Also, eschar is obviously charred skin tissue forming a scab like structure, and looks nothing like gangrene. The wound bed in a burn leaks plasma constantly. Blistering is pretty immediate with heat related burns of a sufficient degree.
