Hi, welcome to HCM.
Pain while micturation, frequency and minimal haematuria are suggestive of urinary tract infection
. You need few investigation like routine urine microscopy test and ultrasonography
of KUB region. It will delineate any infection or any renal pathology if any.
It will be better if you consult your physician or urologist
and take an advise. Mean while have plenty of fluids either water or cranberry juice. It will help in healing process.
Hope I have answered your query.
