My Husband Who Is 72 Is Being Treated For Gerd

My husband who is 72 is being treated for Gerd with omeprazole dr 20mg. Also for fluid on bottom portions of lungs with furosemide 40 mg and Klor-con M20. He has had sharp muscle pain off and on both sides of his ribson bottom and tops of his shoulders. He has had two heart tests done and that is okay. Nothing is making better. What do we do now.
