If my wisdom tooth hurts while coming out, does that mean that I will definitely need an extraction?

My tooth is been hurting for short periods of time during this past years but last week it really scare me that besides the pain this time my cheek was a little swollen and I could not open my mouth but just like 1 centimeter, could this means that my tooth will need to be removed or is that part of the crowning process, or what??? :)
