Hand foot and mouth disease while pregnant

I'm 5 weeks pregnant. My 3 year old has hand foot and mouth disease. Now I have it too. I'm miserable. My hands, feet, and legs itch like a mofo and my throat is covered in blisters making it painful to eat. Because it's a virus, there's no medication I can take to reduce the time, or treat it. Only treat the symptoms. My son didn't itch or have any pain, so I didn't have to give him anything. Any suggestions on what I can do for this?
