I've had a rash on my right groin area and lower abdomen for the past maybe 3 weeks or so. It started off on the right groin and then I noticed maybe a week later that I got another rash on my lower abdomen. They have tiny bumps and it is itchy but I haven't experienced any pain, fever, or any fluid coming out from the rash. The one on my lower abdomen is red and the one on my groin is older so its a bit brown, darker in color. The skin on the oldest rash (right groin) is rough. Recently about few days ago, I noticed that I was getting a smaller rash on my left groin area. I feel like these rashes especially the one on the lower abdomen gets itchier at night. I also noticed my rashes got worse this week. For example, my oldest rash is sort of spreading towards the pubic hairline along the skin folds. And the rash on my lower abdomen is spreading downward. But besides those three spots, I am completely fine elsewhere.
I'm worried what this rash might be. I did some research on the web and there are so many causes like allergies, fungal/yeast, bugs, etc. I never had these rashes before so I'm getting extremely worried about this. What if its an STD/STI or what if theres bugs on me.
I did however went to the doctors the get this rash checked. My physician said it might be fungal or skin inflammation so she scraped my rash to get some skin cells to find out if its fungal or not. My physician said that the results were negative so the cause is not fungal. She suggested it might be skin inflammation so she prescribed me a cream for it which i will go pick it up on monday. The doctor told me to put the cream on everyday and if the rash is still there after 2 weeks I'll have to come in again. But im still worried that what if the cream doesn't work and its not skin inflammation because from what i know i don't have any allergies and I don't think have been exposed to any new chemicals (same soap and i think same detergent).
So what could my rash be?
