Wa alaykum salaam

May Allah grant good and healing for your child. Ameen.

Certainly, you’re concerned for the health of your child. I recommend following the advice of the medical professionals, allow them to do their testing to learn more information and to continue making dua.

I am not a doctor and am unable to diagnose or to suggest treatment for such a condition. I do suggest listening to the advice of the medical professionals. InshaAllah.
