Chafing & bleeding boobs!

Anyone else suffering with really bad chafing from the extra heat, it's agony and flesh is raw. It's not really the thighs as they don't touch and I wear trousers but it's higher up. Also stretch marks around boobs are so itchy and tender they've started to bleed. Anyone else had the same and found a solution?
