i really don't know whether or not actual blood loss can actually lead to this or not, but i can tell you just from my two seperate c spine surgeries i had to have within only a nine month perod i somehow managed to develop ALOT of scar tissue on the inner(inside my neck) surgical area to the point my NS told me it took him like an hour and a half just to actually just cut thru it to reach the spinal column to place my hardware. he just stated it was very thick and fiberous, but i only had lost a "very minimal" amount of blood during my surgery from what was actually in my op notes from that first surgery. i just think in many cases, some people will develop scar tissue much more readily than others.
tho i personally have never heard the blood loss scar tissue connection, anything is possible when it comes to the human body. that much i DO know. i just don't really understand just how one could affect the other in some way, you know what i mean? unless it comes down to a chronic type of simple inflammation type of thing maybe? anytime blood is sitting in an area its not supposed to be, it can irritate the areas in certain ways, it would really depend upon just how reactive that area is to blood products. but only having "just" blood loss from a surgical procedure, that would seem a bit odd since there would be no real connection between the two themselves type thing? not that i am aware of anyway. interesting topic tho. i hope you find some answers with this.
but creation of any scar tissue is really a very basic body response to any level of injury or insult to the body. too much would be kind of a hyper uncontrollable type thing in some ways? just finding out/researching what actually stimulates scar tissue growth itself within what body system, may help in giving you some good reasons for it. just a thought. if you do happen to find this out, please pop back in and let us know? just curious why half my neck feels wayyy too solid in there with it. marcia
