Translation of "Swell" in Japanese

The toothache made his face swell up.

歯痛のために彼の顔ははれあがった。

My hand would swell up and the pain would come back.

手が腫れ 痛みが再発する

In addition to a thick fog, there was a heavy swell.

濃霧に加えてうねりも高かった。

Perhaps she's trying to mimic kelp or algae moving in the swell...

‎潮流にゆらめく海藻を ‎マネしているんだろう

That is protected with a big piece of kelp forest, 'cause the forest itself actually dampens the swell.

‎広大なケルプの森だ ‎森が荒波の衝撃を ‎吸収している
