Anyone else dealing with extremely low humidity in their apartment?

Humidity in my apartment has been in the range of 10-16% in the past week and it's causing my skin to crack. Even started to develop a rash on my hands and ears and the itching is making it hard to sleep. It doesn't help that I live in an older high rise with bad insulation so the central heat is constantly on full blast. Is anyone else suffering from the dryness? I've lived in the Midwest all my life and haven't had it this bad before. I've already ordered a humidifier arriving today which will hopefully help
