constant itching

For the last 2/3 weeks I have been tearing at my skin to the point it is red raw and bleeds, there has been no changes to mybwashing detergents or shower gels so I'm confused at what this could be. I've come to realise today I think I have a mouse problem in my home, could this cause my constant itching? Or could it be something more serious to do with my health, anyone experienced similar?
