I too have problems with costochondritis.
I am not sure how much you know about
it. It was described to me from my doctor as an inflammation of the tissue that connects your ribs to your sternum. It can be brought about
by many different things, and depending on how your body handles it can be mild, or very painful.
One of the main questions to ask first off, is how autistic your daughter is. I hope you don't mind the question, but depending on her capabilities depends on what she can and cannot do, and I'm sure what she will allow you to do or not do.
As far as treatment with medication they will probably do (if they have not) several anti-inflammitory types of treatments. I was started on Naproxen (Aleeve), then went to Ibuprofen, then something else, and finally ended with Celebrex. Celebrex was the only anti-inflammitory that did me any good at all. However, this will all depend on how each works with your daughters body.
One of the things that I found helped me as well was an ice pack placed in the middle of my chest in 15 minute bits throughout the day. It didn't make the pain go away, but it did numb things and it didn't seem as painful for a little while. Also Tiger balm and/or Icy Hot might be worth a try.
My doctor also gave me anti-inflammitory shots that helped a great deal for a few days then the pain started coming back full force again. Yet another thing that was done was a steroid injection, and a "midrol dosage pack" which was a weeks worth of steroid pills that you take a whole bunch of the first day and then take one out each day or something like that.
If you can one of the things that might make the costo not quite so bad, is to have your daughter avoid moving her arms if she doesn't have to. Anything that involves moving your arms tends to put pressure of some sort of the area right in the middle of your chest, where the costo inflammation is at. For me things like washing my hair, brushing my hair, putting on a coat, putting up dishes, hanging clothes, making the bed, and so forth are what aggrivated the costo the most. Pretty much anything that moved the middle of your chest.
I wish you and your daughet the best, and I applaud you for being a great mom and seeking help with this - the initial reason I found healing well was from doing a search related to costochondritis, and this has been a great home ever since. You might also want to go up and use the search option at the top of the forum and do a search for costo - every couple of months a thread pops up in relation to it. Also - the fibromyalgia forum was where I initially found my information, you may consider asking a similiar question there, or doing a search of that forum as well!
