I have had an itchy/blotchy rash since my winter holiday to Tenerife. The rash is on my arms, legs and back. My doctor gave me a cream and antihistamines but they didn't help. I have had a liver function test and allergy test done but it revealed nothing. The rash appears to be under my skin.

The Answer

The symptom of itchiness in the skin usually prompts your general practitioner to think about histamine release and other chemical messengers being released in your skin.  Your skin may be reacting to a trigger, which your general practitioner has investigated with an allergy test .   The common causes of itching include  the following: contact dermatitis, atopic eczema, psoriasis,  pityriasis rosea and urticaria.

Itchiness is one of the most commonest presenting dermatological conditions encountered in general practice and rarely is there a need to perform blood tests or be referred onto a specialist.  When it has been decided to offer blood tests these may include the following: FBC, ESR, U&E, LFT and TFT.

The liver function test you mentioned and the other  tests mentioned above may have ruled out  itching due to uraemia, diabetes,  hypothyroidism, hyperthyroidism and more sinister causes for your itching.

We are unable to diagnose your condition and so you will need to discuss with your general practitioner whether there is a clinical need to be referred onto a specialist.
