Hi Ady,

I'm fairly new here in terms of posting, but I have been all over this forum trying to put a name to my symptoms and find solace. That combined with an excess of anxiety-induced, frantic google searches and scanning of research papers, I hope I may offer some consolation.

To begin, if your anxiety is stemming from the fear that you are again concussed, dispel that now. As you will find on many a post and via the word of the more experienced here, it is highly unlikely that you have suffered a concussion without actually striking your head, and blast physics tells us too that you would more than likely need to injure another part of your body in conjunction with your brain. For those who are concussed in car accidents without a blow to the head, they typically crack several rips if not breaking some other bone in the body.

Trust me though, I have been exactly where you are now and continue to be there despite finding a host of better coping mechanisms and logic. I still become anxious and wonder what sort of physiological impact walking heal first might have or turning to quick or even a speed bump. In all those cases, I have had no incidence of concussion as I could continue to live my life. Last week I drove 14 hours in an RV to move into college, and I am perfectly fine, and RV's, should you sent elsewhere than the driver's or passenger's seat, is extremely unstable and wobbly. The other day, I planted my foot hard and made a post, detailing effectively that I experienced a sharp pain and subsequent symptoms. I am now feeling slightly better after 48 hours of normative behavior and performing some therapeutic exercises. If I was concussed thereafter, I would be going down a rabbit hole.

As far as the sensation of jarring, hopefully you have done some research throughout the forum and come to some more sound conclusions concerning what is going on. Anxiety and introspection can seriously amplify how you perceive the movements of your body. In all likelihood too, your vestibular system acts differently now following the concussive event your experienced, which remains untold, wherein your sensations feel amplified. I and another who I have communicated with on this forum experience something similar where even the smallest movement generates a subtle pressure in the brain as if we are moving much farther than we are. I use to ask my girlfriend all the time, "Did my head move?" or "How fast did it move?". The answer was usually no, barely, or just a normal speed. As a side note, you be surprised how much my life and relationship with her has improved since I stopped asking these questions so frequently and took control of my anxiety.

Regarding your assertion that there could be a neck issue at play, I am not the expert on the physiology on this so hopefully someone with more expertise (Mark/Jomar) can offer something more concrete, but it is certainly possibility it is at play. The sharp pain I described in the post concerning a quick step with the heel seems to be derived from a neck issue, and perhaps that was a trigger for my migraine, though that is speculation. Honestly as long as I am not concussed, life goes on. What I have experienced in the last few days has been some swelling around the cervical spinal cord, and, as you say, a stiff neck. It may be likely too that your shoulders are tense as well, especially considering you were shadow-boxing. Perhaps trying gently massaging those areas to see if any relief is offered. I would like up whiplash therapy and neck strengthening exercises as well, as I often find relief therein.

To conclude, the stress is definitely getting to you as well. Though I not entirely if the inflammation would be predominantly stress-triggered, a myriad of symptoms can arise as you will invariably find in most anxious posts on this forum. Try to relax and perhaps meditate just to clear your mind. I do not know what your original injury was, but as you say, in the past you would not have thought twice about it. This makes me think that you have definitely done some reading on this forum, and though that is not the best piece of advice for us, in terms of accruing a concussion, it is usually correct. Furthermore, in all honesty, I have no idea about the possibility of a pinched nerve and the consequent lack of oxygen supply, but I think for now it can probably be attributed to vestibular, neck, or even migraine issues. If you are feeling off, it is because you are trying to see if you are. Trust me, I have been there and I think all of us probably have at some point or another.

Anyways, I hope you feel better soon. I would probably avoid shadow-boxing, and the general concept of boxing, given it seems you have PCS. If you want to blow off some steam, stationary bike (if you have access) or brisk walking with good posture have been good alternatives for me. As someone who played soccer for 10 years and wanted to play in college, I know it's tough to say goodbye to exercising if not even moving like a normal person, but so it goes. If you have any questions, feel free to ask them. You may wish to detail your original injury(ies) so that others who may chime in can offer more complete advice.
