The nerves that run through the skin on and around the head can take a long time to heal, many months or longer for some. They have nothing to do with the brain or its function. But, the sensitivity can be very uncomfortable. That discomfort can trigger anxiety.

Anxiety can manifest as chest discomfort.

It is helpful to try to differentiate the different discomforts.

I'm confused. You said:
[towards 2 weekends after the incident i found my self driving to the shop and i went into a full blown panic mode i rushed up to the hospital told them my symptoms ]

Did you intend to go to the shop or was this an episode where you don't know why you were driving to the shop ?

You lack of punctuation makes it difficult to understand everything you say.

Many of us find we need to spend time rereading and editing our posts so they are easier to understand. I rarely post something without rereading it a few times. Otherwise, It would not make sense.

btw, I once suffered a trauma that affected my head, neck and shoulder. The ortho put me through some range of motion and other tests that caused chest pains later that day that were symptomatic of a heart attack. After lots of cardiac tests, the skeletal-muscular problem was resolved and the pain attacks went away. A PT believes I inflamed something in the shoulder to neck nerves that caused the chest pains to come and go. I have had it once since and PT or chiro has resolved it.
