What is Di Dang Tang Pulse, Tao He Chen Qi Tang pulse??

Hi! I recently attend my first week of SHL class, however I am not up to the pulse class yet. I come across a female patient with hard palpatable lower abdominal mass mainly in the center but extend bit to the left side around ren 3, st 28-29 acupuncture point area. Patient mainly feel the pain and discomfort on the left side more than the center.  The discomfort and pain occur just before and though out mensturation. Beacuse of the abdominal mass, she have to go to toilet for unrination very frequently, there is no inhibit urination.  From my limited pulse reading skills, her pusle are slightly slow, thin & wiry. Patient said her slow heart rate is because of her cardiomyopathy 11 years ago. Can anyone help me out with the pulse different between Di Dang tang and Tao He Chen Qi Tang?
I am thinking about this 2 formular becuase the lecture mention mid abdominal masses use DDT and on the left use THCQT. Thank you!!!
