Soak,

The rate of complications from chiropractic treatments is extremely low. The tell tale sign is that chiropractors have very low cost for malpractice insurance. MD's pay much more for their malpractice insurance.

Yes, there are a few catastrophic injuries but those same injuries can be caused by an aggressive physical therapist or massage therapist. 180 thousand (180,000) patients die each year due to 'medical' mistakes.

The medical community, the AMA to be precise, has tried to bad mouth chiropractic treatments for decades. The chiro's sued and won a court order for the AMA to stop their misinformation campaign against chiropractic.

The activator protocol is a very gentle system. I highly regard it and wish I could find a good practitioner here in Idaho. My activator chiro in California was a true healer.

I think with most hits to the head the neck takes some of the force also, that's a good reason to get checked by good chiro.

Soft tissue as well as the vertebra can be affected by the trauma of concussion.
If you can find a chiro that uses other treatment modalities along with gentle adjusting I think you can get some good benefits..

Look them up online and read about them or email/call and ask about training, modalities used etc..
Maybe ask about a free evaluation visit.
