Ben,

Answer you own question. Sit down for one minute and ask your self can kissing give me a concussion, you know deep inside what your conclusion will be.

I had a lot of difficulty defining what was hurting me or what was anxiety after my accident. I would draw from past experience pre accident and ask would this have given me a concussion before my accident? If not then you have to chalk it up to anxiety.

Anxiety will lie and lie to you all day and night, you need to recognize the lies, call them for what they are and tell yourself the truth. Sometimes it takes over and over again till the storm settles down.
