If you notice a red, itchy area around your neck, you may have a rash. Rashes like poison ivy and hives may go away without treatment, while other rashes like dermatitis and scabies may require prescription medication, according to the Mayo Clinic. See a doctor to determine the cause of your itchy skin. If your doctor approves, you can use home remedies to help treat the problem while it is healing. Using home remedies will help prevent you from scratching the itchy area around the neck, thus making the rash less noticeable.
Wear cotton clothing and other natural fibers, recommends the Mayo Clinic, such as 100 percent cotton clothing, which is soft and will not irritate the skin like wool or polyester. Wear clothing that is loose fitting around the neck to prevent the fabric from irritating your skin.
Apply a thin coat of aloe gel over a poison ivy or poison sumac rash every two hours, suggests Health911.com. Purchase aloe lotion over the counter at the drugstore or grocery store, or buy an aloe plant and break open one of its leaves.
Wash your clothing, bedding and towels in unscented detergent that is formulated for sensitive skin. The Mayo Clinic recommends running an additional rinse cycle on your washing machine to help remove chemicals from your clothing that could irritate your skin.
Make a paste of vitamin C and water to help soothe itching skin, says Douglas Darr, Ph.D., assistant medical research professor at Duke University Medical Center. Crush two vitamin C tablets and add a few drops of water to make a paste. Gently coat the afflicted area on the neck with the paste and allow the area to dry.
Take a cool bath. Toss a handful of baking soda into the bathwater to help soothe the itchiness and irritation of a rash, then soak in the tub for 15 to 20 minutes. Repeat as necessary to help reduce the urge to scratch.
If you don't have baking soda, use a handful of colloidal oatmeal in the bathtub instead.
Consult a doctor if your rash becomes infected or spreads.
