Could you help me understand this text?
Sorry for the lengthy quote...
Quote:
1. Pain is not always helpful in letting you know the location of the problem.
2. Sometimes pain is felt in one part of the body, but it is actually caused by an injury or illness in another part of the body.
3. This is referred pain.
4. For example, the pain associated with a heart attack may be felt in the left arm, even though the heart is in the chest.
5. An ulcer or other irritation of the stomach may be perceived as pain in the shoulder.
6. This is because during fetal development the nerves that attach to different organs come out of the spinal cord at levels close to where those organs are located in the fetus.
7. However, when the organs migrate to new positions as the fetus grows, the attachments that lead from the spinal cord stay in the same place.
8.As a result, we feel pain as if the affected organs are still located where they were at early stages of embryonic development.
I can easily follow sentences 1 through 6.
But in sentence 7, though I can see that, for example, pain related to a stomach ulcer is felt in the same place to both a fetus and, say, an adult, how can this explain the pain is felt in the shoulder, not in the stomach?
And in sentence 8, I am at a loss. The whole sentence is vague to me (though not grammatically), and again how can it explain the disparity between the location of pain and the location of the problem?
Something in me says it should be an easy and straightforward reading, but I'm having a really hard time piecing it all together.
Could you help me on this?
Thank you so much.
[edit] Oh, on second thought, I can't understand the causation between sentence 5, and sentences 6,7, either.

shcho23 But in sentence 7, though I can see that, for example, pain related to a stomach ulcer is felt in the same place to both a fetus and, say, an adult, how can this explain the pain is felt in the shoulder, not in the stomach? In the fetus the stomach was near the shoulder. In an adult the stomach is not near the shoulder, but the nerve connections are the same.

- In the fetus the stomach was near the shoulder.
- In an adult the stomach is not near the shoulder, but the nerve connections are the same.
- The body "feels distances" between places the same way in an adult as it did as the fetus because of the way that all the nerves are connected to the spine.
- The organs move to different places as the fetus develops, but the body still perceives them to be where they were originally.

It does help. Thank you for your kind reply.
As far as I understand, I guess the attachments - things that cause pain - for the stomach and shoulder are very closely located (both in the fetus and in an adult), so somehow they affect each other, or even confuse each other, causing the pain felt elsewhere instead of where it should be. Could this be about it?
