Hello Doctor - I Very Recently Did ECG, Ultrasound In

Hello Doctor - I very recently did ECG, Ultrasound in Abdomen, Chest X-Ray, CBC and LFT. In ultra sound it is identified i have stone in my right ureter junction causing mild hydroureteronephrosis and I am able to pass urine without any issue but sometimes I get pain in my bladder in chest X-ray it was also identified i have bronchitis in my lungs. Also I did CBC twice in last two weeks and my ESR had increased from 13 - 22 mm/hour and i feel burning sensation all over my body. My physician says it is because of bronchitis and hydroureteronephrosis. I am having burning sensation since last two weeks and because of this I got few black marks in my palms, feet sole and couple of other places.

Request if you could advise what is causing this issue?
