I have a rash on my wrists, arms, chest and stomach that is extremely itchy. The rash is made up of small, red bumps and there are also lines that look almost like scratch marks. The only thing I can think of are poison ivy and scabies. Last wednesday I was at the barn filling the hay mangers, so I was thinking maybe a hay rash? I've tried looking online, but I'm not getting much from it. My mom called the emergency room just in case it's scabies, but she said she couldn't do anything because the pharmacy is closed. I'm freaking out not only because I'm supposed to babysit tomorrow, but because I really wanted to go to the barn to audit a clinic. I know that scabies is highly contagious within contact, so I don't want to spread it any further.
