I’m on W5R1 and up until now I’ve had no problems in this area at least. Last week however I think I had some chafing inside my under armour sports bra. I didn’t notice anything at the time but the next morning had pain and gradually it became very inflamed and I’ve had to get antibiotics. Im now very nervous of running again in case I get further bouts of mastitis. So any suggestions please - how to avoid this happening, best running bra? 😭 thank you!
