I am in my 4th year with Grovers. With me, it got worse as I also had skin bleeds easily ( treat spots wit hydrogen peroxide and wash garment/sheets).
I am a lot better now but still itch. But most of the skin bumps are gone. My treatment was/ Triamcinolone cream and Sarna anti itch lotion. But what also helped greatly was and is Light therapy in the Dermatologists office . A full box treatment(long light bulbs).
at 3 days a week maxing at 4 minutes per front and back each. Now I'm once a week at two minutes. But I skip a lot. Its a slow treatment. I still use the cream and Sarna as needed.
Good luck.
