My Wife Had A Bad Fall 4 Weeks Ago And

my wife had a bad fall 4 weeks ago and has spent quite a lot of time in bed. she now has very bad burping, burning pain in tummy and generally unwell, I have propped her up as high as I can with little relief. our doctor just added zantec to her already pariet x 2 daily. she has previously had a nissens. I give her gastrogel after each food intake. is there any thing else I can do. is there a charge for this information?
