It's not about the spinal cord, but about the bone. These are two different things.
The spinal cord lies next to the spine. It is surrounded by bones. It is part of the central nervous system.
The bone marrow is hidden within the bones themselves. The bone marrow makes blood.
Sometimes the bone marrow swells up and starts to hurt.
The first time this was noticed in pregnant women in the last trimester of pregnancy. Now it is found more often in young men.
Usually everything happens in the leg bones.
So until now and have not figured out the reasons for this outrage. The bone marrow makes blood, so it has a very close relationship with the blood vessels. Either blood clots fly in there, or blood clots dissolve worse in pregnant women, but something clogs up there.
The victims' legs suddenly start to hurt. Against the background of complete well-being, they suddenly begin to complain of severe pain and cannot walk. It is not the joints that hurt, but the bone between the joints. Poking your finger there will hurt.
The entire medical history consists of three steps
During the first month, everything twists and starts to hurt.
Then another month or two it hurts as much as possible.
And finally, for several months, the pain gradually subsides.
Survey
Swelling in a sore spot can be seen on MRI after a few days after the onset of pain. A regular X-ray will show something only after a month. The bone in the affected area will look noticeably thinner than it should be.
In fact, more often some kind of infection or tumor hurts in the bones. Therefore, a sick person is examined up and down.
What will happen next
Everything will gradually pass in 3 - 9 months. Usually there are no consequences.
