Hello Nancy , burning micturition is a common problem ,but you mentioned that there was blood in the bladder some time back, but what was the reason of that blood collection? So now pl go to a lab and your's urine should be tested by a pathologist. If more than 4-5 pus cells and RBCs are in the urine pl consult a nephrologist
. If no pus cells , no RBCs in urine , on oxalates than need not to worry, drink plenty of water as will produces plenty of urine and there will be relief. Good luck and enjoy healthy life.
