HI, thanks for using healthcare magic The red rash may be intertrigo which is inflammation that occurs in the body folds. It can also occur in the armpits and under the breasts. Moisture, heat and friction make it worse so treatment of these areas helps. This means : (1)wearing cool non restrictive clothing (2)separating the skin folds with cotton or linen material or barrier creams such as petroleum, zinc based creams (3)using powders to help dry the area Sometimes bacterial and/or fungal infection can occur along with the inflammation and the use of an antibacterial and anti fungal cream would help. I hope this helps
