I am a woman and I have Grovers. I am 84. In the beginning, it never stopped itching. Now, about a year later, it comes and goes. I try to ignore it. At the same time I got Grover's I was tested for Mercury poisoning. I tested positive. I stopped eating fish with the most mercury about 6 months ago, and I think that's what lessened the itching. I guess the only way I will know is to wait another 6 months and get tested again. My suggestion is to try the prescription creams recommended by other victims. I never tried cilantro.
