Hello there opal my friend and fellow chronic IT swelling sufferer.

I cant remember how much I paid but I just picked it up from a chemist. Give it a go it can't hurt thats for sure. It should give you some relief from the rawness and crusting, but just be wary of the stickiness.

By the way, I think the ITs swell so much to try and compensate for the overly grossly patent airways we now have.
