I do not have any personal experience with burns but I do with surgeries and healing wounds. I have had 23 surgeries to date. One in particular may be similar to your sister. I had a very bad abdominal infection, (very long story), and as my skin, tissue, and insides died off, they did numerous surgeries to keep removing dead infected areas. My wound was also left open to heal from the inside out. They packed it every day with clean dressing and antibiotics. I still have a massive hole, looks like a small cannon was shot into my abdomen, but it has all healed. I have very hard areas around the wounded area. It is scar tissue. When you have an extremely traumatic injury, especially ones healed from the inside out, you will develop a very large amount of scar tissue. Way more than you see with a cut, or even a surgery that they stitch or staple shut. Most of the area does not hurt or cause problems other than looking very odd. Whenever I had the hard areas appear rather quickly after surgery, it was the normal, non painful scar tissue.(this is not medical advise only what has occured with my body in the past) But I have also developed some areas that are painful all the time and get worse with movement. The doctors informed me that this is called adhesions. They are a little deeper than the hard areas, and further away from the actual wound area. The adhesions take much longer to appear and they attach themselves to something inside like muscles, intestines, other organs. Unfortunately there is nothing that can be done for these, (in my case) as the only treatment other than a physical therapist massaging the area to try and break it down, is another surgery to remove all of the scar tissue and the adhesions. They said it would help for about a year with some of the pain, but it would scar in the same area to replace what they take out, only each time the scar gets bigger and deeper and causes even more problems. Due to the nature of my illness, I take an extremely long time to heal, so by the time I got over the surgery they would be back only worse. So I opted not to have them removed. I would still ask the opinion of a physician or wound specialist about the areas you are concerned with. Please also tell her to be watchful for any pain that develops down the road after all is healed, as the adhesions may develop due to the packing technique they are using. I hope she is better soon. You and she will be in my thoughts.
