An inflamed appendix
means that this is redder and bigger than usual and is swollen. It may or may not clear on its own. The best assessment can be done only on the operating table once the appendix is seen. Usually, if there is a sign that this appendix can get obstructed, then the appendix is removed as it does not subserve any important function in the body.
Wishing you the very best for your surgery.
Hope this helps.
