It's hard for me to understand too! DocSarah, please help us understand!
1. Can the scarring \"spread\" in the case of chemically induced AA (myelogram, ESI, etc) as opposed to mechanically induced AA (surgery, etc)?
2. What are the definitions of diffuse damage and focal (localized) damage?
3. What are the differences between them?
4. Is it that the chemicals travel in the spine? Can they go upward as well as downward?
5. I guess scarring occurs because of an insult. So, if the insult is local, then is the scarring also local? If the insult is spread, can the scarring also spread (or seems like it's spreading)?
6. Diffuse or focal, chemically induced or mechanically induced: How do their symptoms differ from each other? Are locations and/or severity of symptoms different in general?
7. How can we assess or \"measure\" the progress of AA? I think our pain level and symptoms can be influenced by many different factors, such as the level of activity as well as inactivity, one's medical history, aging, stress, etc. In some cases, it might be a clear-cut thing. But how do we know which cases are such cases?
I probablly have more questions that I still don't have any answers for, but I thought the questions above when I saw Ang's post.
Thanks.
