question: My boyfriend has very itchy skin and has developed rashes and red bumps on his body in different areas. It started in his elbows. He refuses to go to a doctor to get it checked out and I'm afraid whatever it is is contagious! We have a dog so I wonder if it's something she brought in. But I just had a bump between my toes and itched it and it popped and I am now I'm excruciating pain and there is a red spot there now. I don't know if the two are connected but am wondering of it is a fungal thing or some sort of bug. How can the doctor even know?
