I have a lot of allergies and am a very "rashy" person anyway, but a couple of weeks ago I got this round red rash on my thigh. I actually thought it was ringworm at first, but it doesn't have the "ring" to it.It's all red and rased. Does ringworm have the "ring" everytime? I have no idea where I would get ringworm from, I'm a stay at home Mom, and no one else has it, and I've checked our cats, but who knows. I was taking benadryll but it didn't help to get rid of it, only stopped the itching. When I put penaten paste on it, it starts to get better but it never really goes away. Now it's starting to spread in little itchy red bumps around it. There is no way I can get to the Dr. for at least a week. Anyone have any idea's here?
