Can't Fully Open Mouth After Wisdom Tooth Extraction. I Think a Bone Spur is Causing It? (photo)

It has been 17 days since I have gotten my wisdom teeth taken out and i can still barely open my mouth past 2 fingers. I feel as if something is preventing it. When I stretch my mouth it's a pinching pain that and almost a cartilage like texture. I am wondering if this is a bone spur or something. I have an appointment to clean my teeth but i'm not sure its possible if i cant open my mouth wide enough. I am also worried that my mouth will stay like this forever if its not taken care of.
