I read your question about anxiety, and I don't want to feed into that. But I do want to tell you a better approach.
If you have a pain or a symptom of some kind, the worst thing you could do is google it. And definitely do not try to fit the symptom to a diagnosis. That's your doctor's job.
If you have a pain or a symptom, write it down. Notice other things that might be slightly off. Think about any recent changes you've made. Then call your doctor and talk to the nurse. Let him/her know what is concerning you and do your best to answer their questions.
Your doctor does not need you to diagnose it for him/her. You didn't go to med school. Your doctor did. Be a good patient and answer questions. But do not think that you are qualified to diagnose. That is a mistake too many of us make.
Sorry, never heard of a "Trap Injury."
