Advice on Hearld Patch please!

From reading peoples comments I am getting the impression that there is a relationship between the lenght of time you have the hearld patch and how long you will suffer from PR... Am I correct? Does the hearld patch last for the entire duration or can you still suffer from the rash after the hearld patch goes away?

In my case the herald patch was the last thing to go. It took a couple of weeks to fade after all the other spots had gone.

This seemed to be true for both times I had PR..... Once the patch faded my PR started to clear.

My herald patch is still fresh right now. Maybe after a couple of weeks I could share mine. I am currently in the stage of having small bumps in random areas. Good thing they are not as itchy as compared last week. I think vit C and medication helped.

So?  Would scratching off the Herald Patch help?  Would it shorten the duration?
