I was diagnosed with Grover's Disease last year after I had Covid. Received steroid injections every 2 weeks. My hair fell out, and my skin became very thin and bruised all the time. In other words, the treatment was worse than the disease. The outbreak subsided for about six months, and now it is back and it itches evermore. The best to help me during the outbreak and itch is to take a cold shower and apply Witch Hazel to the skin before bedtime. The latest discovery for me is drinking pure Matcha tea powder from Japan, mixed in hot water with no sweeteners added. Try to stay cool and stay away from stress if possible.
