Update: saw my dr this morning. It is definitely a “burn” caused by my sweat. Top layer(s) of skin are gone, not merely responding or secreting. There is scabbing as the skin tries to cover & regrow. No good! Dr sad it was quite serious, and while not common…it us not altogether uncommon for salty sweaters who do not cool off or rinse off during exercise or prolonged sweating. No “cure,” just prevention.
I’m more predisposed to this reaction bc I am (1) a salty sweater and (2) prone to naturally dry skin.
Prevention:
1- RINSE, RINSE, RINSE. Get the salty sweat off during exercise!
2- use ointment BEFORE exercise kit n body parts/ares where sweat can pool or where chafing may occur. Irritated skin is compromised &much more likely to “burn.”
3- shower ASAP post exercise or sweating. Mild soap & water, dry completely & moisturize with good non-watery ointment/cream.
