September 12, 2010 Lawrence Jaeger provides Skin Rash treatment for itching skin at Advanced Dermatology Associates in New York. If you’ve recently started itching your skin, and you’ve been hiking, camping or enjoying the great outdoors recently, you may have a skin rash. Typical skin rashes from poison ivy, poison oak and poison sumac occur when these items come into contact with the skin. You’ll see a red, uncomfortable and itchy rash that will show up with lines or streaks and has blisters or large raised areas that are hives. Certainly, you may want to consult your doctor like Dr. Lawrence Jaeger of Larchmont, New York, to have the area looked at by a professional. Many home treatments are available for rashes of this type, including using wet compresses or soaking the area with cold water. You may need a prescription medicine that you can receive from a doctor like Dr. Jaeger for severe reactions.
