I know “feel pain” means a feeling of suffering in a more general way and “feel a pain” is usually used to refer to a feeling of hurting in a specific part.
But I am thinking whether I need to change “pain” to its plural form “pains”, when I use the phrase “feel a pain” in the following example.
I feel a pain in my knee and left foot.
I mean, do I have to say or can I say something like the following?
I feel pains in my knee and left foot.
