Why am I getting private part allergies and rashes?

You are suffering with perioral pigmentation problem. You have already tried lots of topical applications. Cosmetic advance treatments can help you further like peels and glutathione.

Several factors can cause black lumps. It's sometimes a self-resolving harmless blood blister that happens when you accidentally bite your lip or something more serious like skin cancer. Anyway, always be alert to the piece of the lump being uncomfortable, bloody, or growing in size. It's better to seek counseling from a physician to be cautious.

The combination of these symptoms might direct that you have a commonly occurring skin problem called seborrheic dermatitis. Health deterioration may result in the appearance of red, irritated skin, flaking of the skin, and hair loss. The chief drivers of these are oily skin, a yeast type that is a natural inhabitant of the skin, and hormones. Moreover, you can use dandruff shampoo that contains ketoconazole or coal tar. When you are bathing, don't go hard on your hair and make sure you don't sunlight your scalp because it can result in difficult and painful inflammation.

Jellyfish stings are common and can leave scars, swelling, and itching even after the pain subsides. Applying antihistamine creams can help with itching and oral antihistamines are recommended for swelling. If symptoms persist, a local methylprednisolone injection may be considered. It's best to avoid swimming and running until the scars heal to prevent further irritation.

Swelling and bruising are common for rough activities. A lump may form after injuring the breast. These bumps are caused by blood collecting under the skin. You should monitor it closely. If it persists or causes any pain, seek medical attention immediately. 

The most common reasons behind this are allergies and skin irritation. You should pay attention to the products you use because they should not contain any harmful ingredients. To fight against this problem, moisturize well and avoid using soaps and chemicals that are too harsh.
