Thank you for providing the needed details.
Protein trace can arise in the urine because of stone. However, this stone is not causing the symptoms you are experiencing. You probably have associated infection of the urine too and that is causing the urinary symptoms and lower back pain
. You should get urine culture done and start antibiotics according to sensitivity.Lithotripsy
can be done for this stone if it can be focused.
Studies have shown that if you tend to increase the urinary flow unnaturally by diuretics or beer it causes the ureter
to go into spasm and thus decrease the chances of spontaneous passage. You should just increase the intake of your water to flush out the stone rather than do anything else.
