my dad is coughing a lot please help
So my dad is 55 years old and hes been on dialysis since April, he barely survived. His energy is better since dialysis and his appetite and everything is better except his coughing. I should mention that he smokes and has been smoking since he was like 17 BUT it was never this bad. since he started dialysis his cough is awful and he cant stop it, and on average he starts coughing every like 5 minutes and its not a dry cough and it lasts for at least a 2/3 minutes.
He got an x-ray of his chest and its all fine. They said that its probably water around his lungs from dialysis and they gave him antibiotics. Its been three days since hes taking antibiotics and on today dialysis they pulled more water out, but hes still coughing like constantly and its crazy and his lungs hurt so much and he looks exhausted. he literally cant sleep because of it. if anyone has any tips or advice please help i dont know what to do anymore and he is in so much pain.
