It's small red bumps and if I scratch no liquid seeps. the first place it appeared was in the crease of my knees, and now the underside of my upper arm. I haven't changed soaps, or diets, and had no contact with any of the "ivys" and i have no allergies. to anything. I'm. at a loss and dislike taking steroids and having pink tint on my skin to stop the itch, can you help please?

Detailed Answer:
Hi,
Thanks for writing to us.
From the description provided, I could think of few possibilities like intertrigo, fungal infection, eczema or uritcaria.
As these are present in occluded flexural areas like underside of arm and crease of knee, there is a strong possibility of intertrigo or frictional dermatitis.
I would be able to confirm the diagnosis, if you could upload an image of affected area. The same can be done by clicking on upload report/image icon which is on right side of query page.
Hoping to hear from you soon.
Take care
