Hi, I have written about my itch problems here before...I belong to a Facebook group for one of my itch problems and someone there discovered that when she took her pre workout supplement, her itch went away...she isolated it to and OTC supplement called Beta Alanine. My itch issues are connected to an auto immune issues and a Mast Cell issue. I have been taking Beta Alanine now for about 5 years and IT KILLS THE ITCH...There are over 4,000 people on this FB page and 85% ish of the group find it helps considerably.

It might be worth a try. I buy on Amazon and take 750 mg as needed...the supplement is usually taken by athletes and they dose much higher, so keep the dose lower then the label says, otherwise it could cause tingling on the skin. It is cheap.

Two Stanford pediatricians found this information on Mayo Connect, used it on a patient and it worked...they published a paper about a year ago.

I hope it works for her...
