If I don't pay the mask penalty

No way around it. You have to pay. If you don't pay, this goes to public prosecution, higher fine and potentially jail.

thank you so much.  I guessed it would happen too.  But I really have trouble breathing when I wear a mask and I cannot explain this problem to anyone, I need surgery next month.  I'm just waiting for the appointment day from my dotor, and believe me, I had to pay about 245 dinars with the traffic ticket in a month.

You should have a note from your doctor that indicates that wearing a mask is detrimental to your health. You can't expect the authorities to take your word for it.

Thank you for recommending this.  I will contact my doctor and consult it as soon as possible.

Note from doctor in Arabic and endorsed by ministry of health.  A simple note won't work. And I would also suggest that till then you don't roam around public places without a mask as people will complain and you will get in more trouble.
