Something like this happened to me. I cut myself pretty bad with something that was not clean. I freaked out, my jaw made noise, my throat was tight, and I was shaking like crazy. I was sure I had tetanus. I couldn't remember the last time I had a booster, so that made it even worse. i called the doctor's office and spoke with the nurse. She said that I had a booster back in 2009, so I was good until 2019. I asked about the symptoms and she said if the wound is healing normally with no muscle soreness in the area, and the fact that I'm still speaking to her was a good sign that I did not have tetanus. That was a year ago, and obviously that is what it was. It was my anxiety causing the symptoms. Your injury could easily be the reason. Weather changes can make all sorts of sounds come out. I know this muggy, rainy weather where I live makes every crack louder.
