When you break out in a rash, it's natural to wonder: Did I touch something I'm allergic to?
An allergist or dermatologist can help you figure it out. You probably don't need a doctor if you know your rash is linked to a specific trigger you can avoid, or if you have a mild reaction that clears up on its own.
Chronic sinus or allergy problems can leave you feeling as though your nose is perpetually stuffed. To breathe freely again, many sinus sufferers rely on nasal irrigation, a technique that flushes out clogged nasal passages using a saltwater solution.
"I find it to be the first line of defense in dealing with complicated sinus problems and allergy problems," says Evangeline Lausier, MD, assistant clinical professor of medicine and director of clinical services at Duke University's department of...
If you brush up against something and you get a rash, your doctor may tell you that you've got "contact dermatitis." It happens when your skin touches something you're sensitive or allergic to.
He’ll examine you and ask whether you recently came in contact with common allergy triggers like perfume, jewelry, or latex.

In rare cases, he may want to do a blood test or a biopsy. For a biopsy, he’ll take a small sample of your skin for testing.
Treating Skin Contact Allergies
How you handle your condition depends on what causes it. Many times, you can simply avoid the things that trigger your symptoms. You can also use cold compresses, calamine lotion, or an oatmeal bath to soothe skin and relieve itchiness.

In case your doctor can't figure out the cause, he may recommend over-the-counter or prescription antihistamine pills.
If your skin gets infected because it's open and raw, you may need an antibiotic to clear it up. Symptoms of an infection include:
