considering the symptoms and reports, it seems you are having urinary tract infection
is first line of treatment for the urinary tract
symptoms. If the symptoms persist then you need to do a urine culture and then take the antibiotics according to sensitivity in the report. For the tear in the vaginal lips there is no need to worry. Practicing proper genital hygiene is necessary., ie cleaning with soap and water everytime after urinating and wearing clean undergarments. PS: cannot comment about the homeopathy
drug since we have little knowledge on that discipline.
