A comma typically goes before parentheses if the sentence structure requires it. For example, in the sentence "She decided to go to the park (which was quite crowded), despite the weather," the comma is placed before the parentheses. However, if the parentheses are at the end of a sentence and the sentence does not require a comma, then no comma is needed.
If a comma is needed, it normally comes after parenthesis.
You can use a comma after an opener , so if it is 'Finally' the opener you are talking about, then yes.
NO!!! The comma comes before 'although'. She said, 'I am tired", although he said "I am not tired".
