Translation of "Palms" in Japanese

The sweaty palms, that sense of rising panic.

汗ばんだ手のひらや 高まるパニック感は 共有できないのです

I can place the palms of my hands on the floor without bending my knees.

私はひざを曲げずに両方の手のひらを床に付けることができる。

When he gets up on stage to sing one of his out-of-tune solos, I get so nervous for him that I get sweaty palms.

彼がソロを歌うとき、音程が外れるんじゃないかって、手に汗握っちゃうよね。
