What does "苦しいのか気持ちいのかわからん" mean?


Found it on twitter.

My literal interpretation comes to "I don't know what feels good or bad." Why
would the fish be saying that? What exactly does the phrase mean?




I would translate the original tweet like this:

> このアザラシ、苦しいのか気持ちいのかわからんWWWWWWWW  
>  This seal... Not sure whether it is suffering from pain or just feeling
> good? LOL

The context: The 18-second video in the tweet shows the seal is turning itself
in the water few times in the same position, which may be mistaken for "I am
drowning" act.

One of the users (TTu) replied with another possibility of "I am itchy" act,
to which the original poster (OP) shared some laugh:

> TTu: 痒いのでわ‼︎  
>  OP: なるほどですww
