Rash
Hi Doc

I have just notices a rash on the underside of my upper arm. It is about 4cm long and about 2,5cm height - looks like pin pricks. The little pin pricks were bright red and after about 10 mins went brown. It is itchy.

When does a rash become serious enough to see a GP - what signs do you look for?

Thank you

An itchy, red rash on the underside of the arm is most likely eczema. I would say contact eczema=contact with nickel in costume jewellery, dyes, plants, chromates, medicines etc. Atopic eczema may show such a rash. These persons also have asthma and or hay fever. Apply a cortisone cream for a few days. Any rash that does not resolve within a few days with simple treatment needs to be seen by a doctor. Any rash that worsens on any treatment should be seen by adoctor.
