Mastitis reoccurring

I've made the decision to stop breast feeding and pumping due to low supply and personal issues , however I've developed mastitis twice now. I'm on antibiotics again it's because of clogged milk ducts on my left boob that I've had for over 2 weeks. I've done everything imaginable (besides cabbage leaves) to help this issue.

Nurses, pumped , massaged , hot water soaking, i just want to know if there is Anything that helped clear your clogged milk ducts without stimulating more milk flow? Please help!
