Peter,

Welcome to Neurotalk. You have found a good place and are among friends, even if we don't know you.

First, there is now way anybody, even the finest expert on concussions in the world who can tell you how long this will last. The saying goes, "If you have seen one brain injury, you have seen ONE brain injury." No two are the same.

Although I am a long time believer in chiropractic, often, the 'twist the head and pop the neck' adjustment procedure is too aggressive for a concussion injury. There are less aggressive modalities.

I bet the blood work did not include Thyroid, B-12, folate, magnesium, and D3. These are all important for concussion recovery. You want to be at the top of the normal range. Most doctors use a normal range of B-12 that starts at 200 pcgms/mL to 970 pcgms/mL as normal. You want to be at 1000. D3 needs to be above the top end of the normal range. Folate needs to be above 20. Mag should be at the high end. Thyroid needs to have proper balance.

There are a few things that only you can do. Quiet rest is the most important. It means minimal cognitive and physical exertion. Walks and light reading an minimal screen time. Visual and auditory stimuli needs to be moderated to a simple level.

No alcohol, caffeine, MSG, artificial sweeteners, energy drinks, etc. Minimal high fructose corn sweetener and moderate natural sugar. Stevia and monk fruit sweetener is OK.

Find the thread title Vitamin supplements. It lists my tried and true regimen prescribed to me by my doctor 30+ years go. The brain needs to flush out the toxins from the injury before it can start to heal. it takes a month or two for this to start to show improvements.

Your delayed symptoms means your brain struggles to continue on with the injured cells. You may have engaged in a stressful activity prior to the symptoms starting. Getting drunk can be a common trigger. So can cramming for finals. It finally gave up and let those injured cells die. Now, it needs to repair damaged myelin and glymph tissue before it can start healing properly.

If you chiro has not prescribed icing the back of your head and top of your neck, he is remiss. You should be icing after very treatment and when ever you have a chance. 15 on, 30 minutes off. A zip lock bag with 1 part rubbing (isopropyl) alcohol and 3 parts water freezes into a moldable ice pack. Ice your neck anytime you have a head ache plus any time you get a chance to sit still.

Keep us posted. There are lots of good people here.

My best to you.
