Is there a separate word for pain (in Pali) which the Buddha used to differentiate pain from suffering? Re: The common saying ... &quot;Pain is inevitable but suffering is a choice&quot;.
Wherein by &quot;dukkha&quot; is meant everything from mild discomfort to intense suffering ...
It occurs to me that the &quot;pain&quot; we experience when the &quot;first arrow&quot; penetrates the heart is a separate phenomenon from the dukkha we experience when we react unskillfully to this first arrow.
Logically, therefore, if one's aim were to create a path of practice leading to the end of dukkha, one might expect a different word to be used to clearly discern between the concepts of (1) pain and (2) dukkha and for that word to be used repeatedly throughout the suttas.
I mostly listen to Dharma talks rather than read the suttas. But, strangely, I have never heard a Dharma teacher use a separate word for pain.
Does such a word exist?
Is it used commonly in the suttas?
The Buddha taught 3 types of dukkha:

Dukkha-dukkhata, the actual feeling of physical or mental unpleasantness.
Sankhara-dukkhata, the inherent unpleasantness of the formations.
Viparinama-dukkhata, the inherent unpleasantness of change.

Dukkha is principally defined as the aggregates:

Natthi khandhasamā dukkhā
no pain like the aggregates

They are also called aggregates of clinging [upadana] because they are what is being clung to [upadana] as one focuses on the allure of the aggregates which are the 5 classes of past, present &amp; future phenomena (form, feeling, perception, formation &amp; consciousness).
Craving is a requisite for Upadana which is in turn a requisite condition for becoming.

An Arahant does not cling but is not to be said to be without the aggregates. Even tho his mind is made straight, his five sense faculties remain unimpaired, by which he still experiences what is agreeable and disagreeable and feels pleasure and pain.
To differentiate between physical and mental pain one can use 'kayika dukkha vedana' and 'cetasika dukkha vedana' or more specifically ie domanassa which is sadness or grief and thus a type of cetasika [mental] dukkha.
The Sutta mentioned in the op uses kayika and cetasika to differentiate between mental and physical pain.

They experience two feelings:
So dve vedanā vedayati—
physical and mental.
kāyikañca, cetasikañca
