Hi, I feels burning sensation and a pain at the time of urination and before also..... I feels to urinate but can't ..(small amount and yellow color) Like this was happening rarely But From past 20 days every 4 hour once it happens and stay up to  2 hours if I don't drink enough water immediately . If I drink I can feel better in half an hour... This pain will be at its high at the time of period . I already booked a appointment through practo tomorrow till that I can't tolerate ... Please suggest me some medication note: yesterday periods happened Thanks
