I have red patches and bumps between my breasts from sweating when I wear a sports top. What can I do to help with this?

To help with redness and rash between your breasts due to sweat from wearing a sports bra, it is important to keep the area well ventilated. You can apply a small amount of 0.5% hydrocortisone cream to the affected area twice a day for 5 days, then make sure to keep the area well-aired afterwards. This should help the redness go away in around 3 to 4 days. In the future, it's important to remove your sports bra promptly after working out to avoid friction, prolonged moisture, and the development of pimples.
