Lisa Sanders, 'Dad, I Can't Walk.'  The rash formed rings around a young boy's ankle, and his joints hurt. Was it an allergy?  New York Times Magazine, July 9, 2017.

Note:
(a) "He and his wife considered the possibility of chickenpox, but the child had received the varicella vaccine. * * * He'd [The boy had] also complained about pain in his ankle and another time in his knee. * * * Neither joint [gad] looked red or swollen * * * The father hurried over to the boy. An irregular band of solid red ringed both legs, just above the anklebone.  The boundary between rash and normal skin was well defined and jagged * * * The ankles might have been a little swollen. * * * They [red dots in the rash] were itchy at first but now were kind of sore. * * * no fever * * * The doctor felt one slightly enlarged lymph node on the right side of the boy's neck."
(i) varicella (n; etymology)
https://www.merriam-webster.com/dictionary/varicella
is the medical term for chickenpox.
(ii) talus bone
https://en.wikipedia.org/wiki/Talus_bone
(also known as angle bone, is [the largest] one of the group of foot bones known as the tarsus [Latin for ankle] )
(A) Click "tarsus" and you will see one can not feel talus through the skin.
(B) Ankle joint is formed between the two bones (medical terms: tibia and fibula) in the legs AND talus (altogether three bones).  

(b) "across the boy's buttocks [which is a medical term, corresponding to 'bum' in the slang], were dozens of the same red spots seen on his legs. But here the spots were larger and much darker. And as with the lesions on the boy's legs and ankles, pressure didn't make the rash blanch — an indication that the dots were actually tiny pools of blood deposited within the layers of the skin, a kind of rash known as purpura [accent on the first syllable; Latin noun feminine for the color purple]."

("They measure 0.3–1 cm (3–10 mm), whereas petechiae measure less than 3 mm, and ecchymoses [whose singular form is 'ecchymosis'] greater than 1 cm")
(c) "The doctor thought the child had something more common and benign: an autoimmune disorder known as Henoch-Schönlein purpura (HSP). This disease, first described more than 200 years ago, usually affects children under 12 and is characterized by migrating joint pain and a purpuric rash that is worse in areas of pressure. That would explain the ankle rash — probably a result of pressure from the child’s snow boots — and the lesions on his buttocks. There is no test for this disorder, so the diagnosis is made based on the history and exam."

Henoch–Schönlein purpura
https://en.wikipedia.org/wiki/Henoch–Schönlein_purpura
("HSP is often preceded by an infection, such as a throat infection.  HSP is a systemic vasculitis (inflammation of blood vessels) and is characterized by deposition of immune complexes containing the antibody immunoglobulin A (IgA); the exact cause for this phenomenon is unknown. * * * is named after Eduard Heinrich Henoch (1820–1910), a German pediatrician * * * and his teacher Johann Lukas Schönlein (1793–1864), who described it in the 1860s")

The English pronunciation for "ch" (in Henoch) is "k" and and "ei" (in Schönlein) sounds like "eye" in English.
