I think you shouldn't rely on TCM for the sprain on your ankle. It's best if it is checked by a healthcare professional who can provide the proper treatment for you, especially if you're breastfeeding. I know an orthopaedic doctor who can provide personalised treatment for you. If you are interested, it's located in Mount Elizabeth, the clinic's name is International Orthopaedic Clinic.
I think proper tcm will advise what kind of treatment for you like tui na and accuputure, or some medicine safe for breast feeding. Hope you get well soon.
Pump and dump for that 1 feed if you’re worried! That’s what I do
Try acupuncture
