What Causes Itchy Spreading Rashes On Knees And Wrists?

Hi, On Sunday, a rash started on my knees and wrists and now it has spread to almost all parts of my body. I purchased Cortizone last night and have applied it 3 times since then. The rash is visibly reduced but the itching continues. What do you think it is? Do I continue using the Cortizone?

Hi..
Welcome to HEALTHCARE MAGIC..

I have gone through your query and can understand your concerns..

As per your complain rash on the knees and wrists that has spread to whole body along with severe itching seems to be most probably due to allergic reaction and can be due to a number of causes like Poison Ivy, any soaps or detergents, insect bites, allergy to any food or medicine etc

I would suggest you to consult an Allergist and get evaluated and a thorough clinical evaluation and investigations like allergic tests like Patch test, RAST test, food challenge test etc can help in diagnosis and treatment can be done accordingly..

The tests will help in ruling out the exact cause of the allergen and once you know the cause of the allergic reaction you can avoid exposure to it to prevent allergy attack..

The allergist can advise to oral anti allergics as well as injectable steroids for relief..

As of now you can take anti-allergics like Levocetrizine, Allegra to control the itching and swelling..
Do cool compresses..
Application of calamine lotion can help in soothing the skin..

You can also be instilled an Immunotherapy that will help in reducing the severity and frequency of allergic attack..

Hope this information helps..

Thanks and regards..
