My grandmother is 70 years old. She has been suffering from breathlessness for almost 8 months now. She was diagnosed with infection in lungs. And she was also feeling dizziness and anxiety attacks a lot, so regarding this, the doctor who was treating her for the first 4 months gave her medications regarding blood pressure, heart diseases, lung infection and for anxiety pains. But with that treatment, she did not get relief and her anxiety issues grew more. Now, she is being treated by another doctor for the past 25 days. The new doctor cancelled all her previous medications regarding blood pressure and heart diseases. She is now on medication for lungs infection. Now, she does not feel dizziness and does not have anxiety attacks either. But she does feels breathlessness a couple of times everyday. She also has a lot of swelling on her feet and after analyzing this swelling situation, doctor explained that she has water retention in her feet. She feels pain while walking. On a side note, she has decreased output of urine for more than a year now. So, If you could suggest something regarding this situation, it could be as big as life saving for us. Please, please help.
