I get those darn things too. Aren't they irritating? Here's what I did and it does seem to help.
I get a cotton ball and put some apple cider vinegar (only this kind)
on it and just hold it on there, or put a bandaid on it to hold it in place. Helps on the itch and it's usually gone in hour or two. Hope this works for you too. It regulates the ph balance of the skin. Diana
