How Can chest Congestion Along With Cough Be Treated?

complicated question. Some background. I am type 2 diabetic, and it seems to be under control. a week ago I was given Azynthromycin for bad cough, phlegm in chest. it was a six pack of pills. took two last Saturday and then one a day until meds were finished. still a bit of a phegmy cough; but better. midnight of the 7th, my urine was discolored, sort of rosy coloured. During the day of the 8th, more blood seemed noticeable in the urine. I have been drinking, I do not have an urge to urinate. I have some pain in my lower abodomen. I have suffered from stones in the past. I have been drinking; but no real urnary flow. the odd drip. somewhat constipated as well, when on toilet some bowel movement, and a few drips of urine come out. urine is a dark browny red colour. I have been drinking, thinking to flush system if there are stones; but urine flow is limited to drips.
