Pinyin
yuān
Simplified
㾓
Literal
A sickness radical over 肙 for sound. 《說文》 gives it nothing but 病也 — illness — which is what it does with words whose field is known and whose life is short. Commentators have taken it as the aching that follows use: sour, deep, not urgent.
Shuowen
《說文解字》:㾓,病也。从疒肙聲(舊注多以酸痛釋之;《廣韻》烏懸切,音淵;《集韻》:骨酸也)。

In brief

A word that survives in the Suwen in two places and was already rare when the dictionaries were assembled. In chapter 7 it is the ache in the calf that comes with the three yang’s disease: cold and heat, abscesses below, flaccidity, reversal, and an aching shank. In chapter 21 it is the heart that aches, when true emptiness is there and the one yin governs. Nothing else hangs on the word; it belongs to descriptions where the body hurts sourly and without inflammation, which is why the dictionaries reach for sour.

一陰至,厥陰之治也。真虚㾓心,厥氣留薄,發爲白汗,調食和藥,治在下俞。 一阴至,厥阴之治也。真虚㾓心,厥气留薄,发为白汗,调食和药,治在下俞。
Yī yīn zhì, jué yīn zhī zhì yě. Zhēn xū yuān xīn, jué qì liú bó, fā wéi bái hàn, tiáo shí hé yào, zhì zài xià shù.
The one yin arriving is the governance of the reverting yin. With true emptiness the heart aches; counterflow qi lodges and presses, giving rise to white sweat. Regulate the food and harmonise the medicine; treat at the lower transport points.
本篇厥陰之亟:「真虚㾓心,厥氣留薄,發爲白汗。」㾓讀 yuān,《說文》只訓「病也」,《廣韻》烏懸切、《集韻》「骨酸也」——後世字書皆以酸痛解之,本篇心痛正合此義。第七篇亦有之:「三陽爲病,發寒熱,下爲癰腫,及爲痿厥腨㾓」,腨(小腿肚)酸痛是也。二字之見於全書者止此。其下文即為厥氣留薄而發白汗,故本篇之㾓心與厥氣、白汗同屬厥陰之一串,非獨一症。

It is said: when the third yang is diseased, it produces cold and heat; below, it becomes abscesses and swellings, and also weakness, reversal, and aching of the calf. If it transmits into a withered sheen, and then into a drooping hernia, the illness is grave.
「及爲痿厥腨㾓」——三陽為病,下為癰腫,又為痿厥及小腿肚酸痛;㾓讀 yuān,骨酸也;**「㾓」本篇1見**

How it has been translated

Every rendering below is a decision about which reader is being addressed. There is no neutral option.

Wiseman & FengachingThey render 㾓 as aching in the places where it names discomfort rather than a disease.
Unschuldaching / sorenessHe sometimes supplies soreness where the site is a limb.
This siteachingThe single English word that neither promises inflammation nor asks for a location: sour aching would import the dictionary reading into the sentence, and deep aching would add a judgement the base text does not make. Given that the graph occurs twice in the whole Suwen, it also seems fair not to give it a technical English name of its own.
