I have ckd for about a year recently about 4 mo I been accumulating fluid, so I do a extra day of dialysis 4 days a week. the pas month now, I been coughing, pretty much no stop. I noticed when I walk I have shortness of breath, the upper stomach is straining like pulled muscle. the doctor says I developed allergies and sinuses and asthma. I think it is more that. what should I do...my symptons are not getting better.t
