Cultural Tip
In French, pain is expressed with "avoir mal à" rather than "être". Saying "J'ai mal au bas du dos" is clear and polite; avoid saying "Je suis mal" which sounds ungrammatical. Also, French speakers often specify the exact region ("bas du dos") when describing back pain, especially in medical contexts.
