Prayers for my mother-in-law

Thursday evening Andrew and I took some time and celebrated our anniversary and Valentine's Day with dinner out at our favorite local restaurant.  While there, Andrew's cell phone rang and he saw that it was his parents, but he didn't answer.  Fortunately, he did return the call when we got home, and we learned his mother is in the hospital with pneumonia.  Andrew has been able to chat with her and overall she sounds good, but it's now three days and she is still there.  They know she isn't going home tomorrow either.  The meds are not working like they had hoped.  I'm extremely concerned, and I'll be honest, it brings back lots of less than pleasant memories regarding my dad's illness.  Any and all prayers for my mother-in-law's healing are greatly appreciated!
