Hi Yeal
I have heard of good results from using oatmeal.
One trick you could try which may stop the itching for a short time (shopping trip, driving, visitors)
Put ice fingers inside your pad. The coolness of the ice may stop the itching.
To make your own ice fingers
Get a bix of single use plastic glives ( the ones that the MO's / Nurses use. Cut off the fingers part fill with water tie a knot in the end and freeze them.
