My grandad has fluid on his heart and I am scared for him.... he lives too far away for me to just nip up to the hospital to ask the doctors about it and all results on Google are maddingly unhelpful. I really need to know straight up what it is and my burning question is: Is it fatal? He is old and has had loads of medical issues in the past.
Please tell me straight all the information you know about this. I want to know what's going on with him.
