ーHe told me his eyes have been bothering him since he woke up this morning. I put some eye drops in (his eyes,) but if it gets worse please give me a call and I will come pick him up right away.
「今朝起きてから目が変なようで、目薬をさしましたが、ひどくなるようでしたら電話してもらえますか?すぐに迎えにきます。」
his eyes have been bothering him で「目が変な感じがする」と言えます。
もし目が痛いと言う場合は his eyes have been hurting と言えます。
put some eyedrops in 「目薬をさす」
get worse で「ひどくなる」
I will come pick him up right away で「私はすぐに彼を迎えにきます」
ご参考まで!
