They can take on various forms and symptoms – like rashes and redness, swelling, burning and itchiness of the skin – and can strike out of nowhere, making you yearn for relief. Some of these flare-ups resolve on their own, while others require a doctor's care. But the first step is pinpointing what exactly caused the unsightly inflammation.

If you have sensitive skin, you may break out in hives at the mere suggestion of these triggers.
