Using 胸が苦しい when talking about love


What can it mean when someone is talking about love and they use this phrase?
Example:

> 恋愛感情。
>
> 俺があの人に対して抱いている気持ちは、それなのだろうか。
>
> 綺麗だと思うし、ずっと見ていたい。今日のあの出来事を、忘れたくない。思い出すと胸が苦しくなった。
>
> もしかしてこれは。
>
> 「恋かな」

Doesn't sound like the main character is describing a negative feeling, yet
using 苦 in a positive sense seems quite strange to me... Or is it normal?
Perhaps it even can mean an actual physical sensation? (also seems strange to
me, but I admit I'm not highly experienced in love)




I think it refers to experiencing such strong emotion almost such that it
becomes physical. I think in this case it's referring to the strong emotion of
not wanting to forget (忘れたくない) and that it hurts just thinking about what
happened today.

It's used quite often in song lyrics and reminds me of "it pains me to part",
other people have mentioned "heart-throbbing".
