I often have rashes in the folds of my joints every summer and would have black ugly scars. it sucks because i couldn't wear shorts or sandos! help?

What you describe...: ...Is relatively typical for eczema, a condition that involves dry and scaly skin, and can cause a lot of itch and even changes in skin color when it gets bad. It's often in the places you describe, and it can be very seasonal. Your doctor or a dermatologist should be able to easily confirm the diagnosis and provide treatment.
