What is a red itchy lump on the leg size of penny raised slightly?

A red, itchy lump on the leg the size of a penny that is slightly raised could be several different things, including:

- Insect bite or sting: This is the most common cause of red, itchy lumps on the skin. Insect bites and stings can be caused by mosquitoes, fleas, ticks, spiders, and other insects.

- Allergic reaction: A red, itchy lump on the leg could also be caused by an allergic reaction to something in the environment, such as pollen, pet dander, or food.

- Folliculitis: This is a skin condition that occurs when hair follicles become infected or inflamed. Folliculitis can be caused by bacteria, viruses, or fungi.

- Cellulitis: This is a bacterial skin infection that can cause redness, swelling, warmth, and pain. Cellulitis can spread quickly and can be serious if not treated promptly.

If you have a red, itchy lump on your leg that is the size of a penny and is slightly raised, it is important to see a doctor if it does not improve within a few days or if you have any other symptoms, such as fever, chills, or swelling. Your doctor can diagnose the cause of the lump and recommend treatment if necessary.
