I have had a bad each on my legs for about four years now. I play field hockey, and the rash lines up right where my shin guards are. I have been to three different dermatologists, each one saying that is is from different things, only one of them said it was from shin guards (which I am almost positive it is). I have tried so many different creams, lotions, and ointments but none of them seem to be working. I started wearing sleeves under my shin guards, and even duct taped the backs of my shin guards, but the rash won't go away. Just recently, bumps starting appearing on my back and arms. Does that have anything to do with my shins? Any suggestions on what I should do?
