Ive just been to a medical drop in centre as cannot get a Doctors appointment for over 3 weeks and i saw a young nurse in her early 20's not a Doctor. As last Adrenalin rush near cripple me and made me feel ill all day also intense pain going from across my lower back up to my shoulder's and across them and into my neck. and leaving a dull ache between my shoulder blades and in lower back.. This nurse insisted that Adrenalin rush does not cause pain. and that it must be muscular. Im an X-Rugby player and Cricketer and have a physical job as a Landscape Gardener Fencer.. And i know when i have torn a muscle or injured my back. and this is not this. Since last attack. due to an intense arguement with a family member. and myself trying to keep the peace. It has left me for over a week now dull ache in my lower back and in my shoulder's/ and an occasional stabbing pain below my stomach and in my groin. Hence going to drop in centre. I know from coming across this site that im not the only one who has this happen and that Adrenalin rush can cause intense pain. .Whether this is connected to some other problem who knows. ??. But to be told by a nurse not a Qualified Doctor that i Quote " Adrenalin rush does not cause pain " has left me quite perplexed. We cannot all be mistaken. !!.
Another problem is, and here we get to the original question: muscle contraction, which happens when the fight or flight reaction kicks in.
Many musles that support the lower back, just as the knees and feet are connected to the adrenal glands. So when stress kicks in, the musles contract. This is a normal fysical reaction. A problem occurs however when the musles do not stop contracting! "Gronic muscular contraction is painful because, once glycogen (the fuel of muscles) is burned up from a musle's constant use, acids build up around the nerve receptors.
The muscle becomes deeply fatigued, and no fresh blood, oxygen en nutrients can get to it. The muscle becomes literally starved while the demand of work is still being demand from the muscle by the brain. Pain is the result". Why does the musle not relax after the stress ends? This has to do with sensory-motor amnesia.
"In a nutshell, sensory-motor amnesia is what can result when the muscular system and the nervous system get stuck in a feedback loop. These systems keep sending messages back and forth and the muscles keep receiving messages that tell them to contract. The 'amnesia occurs in the neocortx of the brain. Thomas Hanna has conducted groundbreaking work regarding this. Somatic movement is the best cure regarding this issue according to Thomas Hanna and this is in lines with Traditional Chinese Medicine. the Chinese have for centuries already linked the kidneys to brain issues and lower back pain and knee pain, among others. The recommend Tai Chi or Qi Gong for example. Very powerful stuff.
I first experienced this in my late 20's and probably another 10 or so times since then, I am now in my late 40's.
I have read all the posts before me and a couple have stood out. One spoke of a benign tumor which sounded interesting but for me the explanation of the descending aorta and inferior vena cava which are under extreme pressure in the event of a fight or flight episode tend to get my vote. I think this explanation combined with sitting makes thing worse. I have come to this conclusion as I have had many other fight or flight incidents over the years while standing and I dont recall ever experiencing the severe throbbing pain when standing.
There are probably many other smaller contributing factors but for me and I think many others is that the sitting position is the key.
Can anyone explain how sitting could make the descending aorta and the inferior vena cava create these symptoms worse ? I would guess that like a bend in a pipe it would slow any liquids passing through it down.
It was nice (in a way) to hear I was not alone.
As a footnote I had a DNA test years ago and fond out I carry what they describe as the Warrior gene which I think 1 in 3 males of European decent carry and 2 in 3 maori natives of New Zealand carry. This
I think relates strongly to the fight mode and from experience I can say that although I am a very fair kind hearted person I get very angry with bullies, thieves and the like.
Hope this is of help.
