Hey everyone, I've been lurking for a while but figured it was time to post because of a minor car accident I was in yesterday

Previous history:
- in Feb 2017, I'd flipped off my snowboard and landed on the back of my head on an icy patch of the trail. Felt a little off the rest of the day, didn't sleep well the night of, and woke up feeling very strange. Went to the doctor who diagnosed me with a minor concussion. Took some time off work and took it easy on going out and partying for a while, but was dealing with some serious personal issues between me and someone I was dating at the time

Symptoms included:
- inability to sleep more than 7.5 hours
- being more emotional than usual
- eye strain doing 3D CAD modeling work for my job
- brain fog and depression (I had suffered from depression earlier in my life as well)

- in March 2017 (about 6 weeks later), I was out snowboarding again and fell not too bad on my butt, but the fall seemed to jarr me enough to exacerbate the symptoms I had felt through my first concussion.

- July 4, 2017, I was picking something up off the ground and hit the center of my head on a doorframe, similar symptoms developed in addition to:
- tinnitus (low-volume ringing in both of my ears)
- anxiety about any minor hit to the head

- August 2017, no head injury, but I had been fired from my job, moved out of a house I had been renting with 3 friends and been dumped by the girl I was seeing for a couple months so there was a lot of stress in my personal life

- October 2017, was surfing and the surfboard flipped and hit the R side of my forehead, where I've felt constant head pressure since

And Finally, yesterday, I was slowing down at a stop sign and misjudged when the car in front of me would start moving after his stop and rear-ended him at around 5mph. Initially I felt okay, we exchanged information and I went about my day, but my anxiety kicked in and I didn't sleep too well last night, and today, everything feels a bit foggy and I'm anxious that I suffered another concussion.

To treat my ongoing symptoms in the past, I had:
- begun to exercise again, strength training and some cardio (try to improve blood flow to the brain)
- have bought the vitamins from the sticky thread
- meditate more and try to move more intentionally as to not put my head in a position to be hit

Treatments I am considering after reading about things here:
- neck physiotherapy
- scalp acupuncture

Questions for you guys,

1. Would a low-velocity auto accident have enough force to be concussive?
2. Because this is my 5th head hit of consequence as far as what I remember in the last 12 months, what can I do to try and minimize the risk in the future (obviously drive more defensively and not distracted)
3. What's the best way to find someone to treat the subtle neck injuries Mark in Idaho talks about?

Thanks for the help
