Hi and welcome to Healthcare magic
I dont think that this bump and urine are related. It doesnt sound serious,it looks like som ebenign subcutaneous lesion such as lipoma
or ateroma and it usually subside spontaneously. If there are signs of inflammation you might need antibiotic tratment and if this persists you should remove it surgically. Also, do urine analysis to evaluate this blood in urine which can be sign of infection or kidney
Regards .Wish you good health.
