I bot a pare of lace up bootie heels n wore them only once cuz they were painful and once off, i noticed an air bubble in my skin. how do i rid it?

See dermatologist : The blister is most likely from friction or pressure from the heels. See a dermatologist to have the blister lanced and treated with a topical antibiotic ointment until it heals.

Skin bubble: Blisters form from friction against the skin, but also moisture is needed. Pop the blister and apply a bandaid. To prevent then, change shoes and socks, try moisture control by using spray deodorant on your feet (yes, the same armpit deodorant you buy). This may help decrease moisture and therefore decrease chance of blisters.
