I've noticed over the last few days that the soles of my feet have become quite itchy. And on the one sole there's a bite like Mark. I don't think it is a bite as its tender when i touch it. 

I've read that itchy feet can lead to more serious problems during pregnancy. Has anyone else experienced itchy feet and there were no other underlying problems?

the condition you're referring to would normally include itchy hands and bump as well... Bites can be sore on unusual places such as the feet as the feet are not normally exposed as much.

hope this helips x
