When I eat tomatoes, I get little bumps inside my mouth right after I finish eating them.
I wonder if this is some kind of allergic reaction.
ーWhen I eat tomatoes, I get little bumps inside my mouth right after I finish eating them.
「トマトを食べると、食べた直後に口の中にブツブツができます」
to get little bumps で「小さいブツブツができる」
right after で「〜したあとすぐ・〜の直後」
ーI wonder if this is some kind of allergic reaction.
「これは何らかのアレルギー反応かなあ」
allergic reaction で「アレルギー反応」
ご参考まで!
