I just joined as I believe I may have Grovers. Went to Urgent Care yesterday and doc couldn't figure it out... didn't think to ask of Grover's at the time. Going to my dermatologist on Thursday this week. No itching at all... no pain, no other symptoms... but red spots on my chest that look like bites. Can you have Grover's with no itch? It flared after I did a home sauna session... however, I've been doing my sauna (and other sweaty sports) for over 20+ years. Is this something that can happen so suddenly?
