Based on the history and the image, this appears most consistent with folliculitis (inflammation/infection of hair follicles) which can occur due to sweat, friction, bacterial or fungal infection. The dark spots you are noticing are likely post-inflammatory hyperpigmentation that develops after the rash heals.
Helpful Tips / Word of Caution:
• Avoid scratching as it increases pigmentation and infection risk.
• Bathe after sweating and change sweaty clothes promptly.
• The dark marks usually fade gradually over a few weeks to months once the inflammation settles.
