Worry does not leave marks on your skin. Howe­ver, it may cause restle­ssness. Restless pe­ople sometimes scratch or bump into obje­cts. This can result in bruises forming. Fee­ling tense weake­ns your body's defenses. A we­akened immune syste­m makes bruising more likely. To pre­vent stress-relate­d bruising, you should find ways to relax. Try calming activities, exe­rcising regularly, and eating nutritious foods.

You may have gotten bitten by an insect, which your body doesn't like at all. Sometimes, such bites can result in skin all lumpy and itchy, as you have mentioned.

If you have mild skin breakouts, like small pimples or redness, you can try using a product with benzoyl peroxide. These breakouts often occur when dirt and oil clog your pores, leading to bacteria that cause pimples. Benzoyl peroxide helps kill this bacteria and heal the pimples.

If you experience dryness, it might be due to benzoyl peroxide, so it's a good idea to apply a moisturizer after the treatment.

If it has turned slightly yellow, it may be a minor infection. Using Boroline is fine at the moment. When it is discharging clear liquid, then it is healing. Do not pick it, keep it clean, and look for any redness or increased pain. It will get better in about a week.
