Welcome to the Message board, I´m sorry to hear about your child´s health problems. The symbols you shared are not really enough to get an idea of what may be going on. As you know this is also not a place to do personal readings but if you have a specific question that can also be used as an example for others, then feel free to ask.
If you are looking for more general information about medical astrology, we had a thread on it that you can study as there are anatomical/physiological correlations and also some examples.
Here is a link to the thread: http://schoolofevolutionaryastrology.com/forum/index.php?topic=864.0
All the best
