I think bachi ko nazar lag gai hai , Nazar (evil eye) ki khaas duain parh kar is par dam karna hoga .And let her listen to surah Rehman,even if she is in
coma she can listen .Say good and encouraging things in front of her. i know someone who was in coma for 1 1/2 month and now she's ok,alhamdulillah!
May Allah (swt) give Arfa shifa-e-kamila,ameen!!
