A rash can be caused by a variety of reasons, including allergies, infections, and general medical conditions. There is no single treatment for all rashes. I would recommend that you come in for an office visit. Usually by asking the right questions and examining your rash we can diagnose the cause of your condition and provide a successful treatment.
Skin cancer is becoming increasingly common in the United States. If you have a worrisome lesion I would strongly encourage you to come in to the office for an examination. Most types can be treated when caught early. However, left untreated skin cancer can cause serious health problems or even death. Many patients have told me that they delayed coming in because they were too scared or nervous. Most of the time all we need to do is take a look or do an easy biopsy in the office, so don’t let your concerns prevent you from coming in!

Warts can be treated. The first step is to make sure that the spot is actually a wart and not another condition (such as molluscum) that can look like a wart. There are a variety of treatments that can be successfully used to treat a wart. I have found that most of the over-the-counter remedies do not work well. We usually use either medications, freezing, or lasers. They are all very easy to perform, even on a ten-year-old.
