Hi there,

Welcome to Just answer !

I believe you must have developed what is called as application site dermatitis which appears as rash and itches a lot , as this application site dermatitis is a known side effect of voltaren gel and it calls for discontinuation of the use of this gel.

As the name suggests this application site dermatitis usually occurs at the site of application and it's surrounding areas .

So, the treatment of this condition is as below..

1) stop / discontinue use of voltaren gel and inform your doctor about it .

2) use of topical hydrocortisone ( steroid ) cream or lotion for application the effected area .

3) continue use of anti histaminic drug xergic for 2-3 days ..

4) Inform and involve your primary doctor in this and discuss with him the above mentioned treatment modality for approval.

This rash and icthy feeling shall be over within 5-7 days , if not early with the mentioned above strategy.

I hope this helps..

Wish you all the best..
