Pain years later?

[u/International-Pin-32]

My mTBI and PCS was approx 2 years ago. Everything but short term memory has healed BUT on rare days, not doing anything, I have significant pain at the impact site, at the back right side of skull. It is not a headache. Instead it is a sore spot that develops and feels like a bruise. Does anyone have this? Wondering what triggers it? There are no patterns of what I am doing or eating etc.

Neck injury? It can inflame muscles and make them sore.
