Name that disorder
The first is an “attack” of burning pain and redness of the pinna of one ear and is made worse by a variety of common things: touch, neck movement, lying on affected ear, contact with hot or cold water (drinking or touch) or straining. Depending on the person, it can go on from 15 min to a couple of days. However, a few hours is the most typical length of time. The redness is at the pinna only but the pain can be above/behind the ear and possibly the upper neck, cheek or temple on the affected side. This syndrome has been around for many years but research has been more prevalent since the 1990s. There have also been studies of this particular disorder with having a higher incidence in children with migraines or other primary headaches. It may also be linked to irritation of the third cervical root, temporomandibular joint dysfunction, or thalamic syndrome.

How about this picture? 
There is no particular disorder to this picture, but a red reflex when light hits the tympanic membrane. The red usually starts at the umbo and radiates out. It is usually a triangular shape radiating up (anterior inferior) along the TM and canal wall. Other terms to describe this are Politzer’s luminous cone, Wilde’s triangle, light reflex and cone of light.
