I have it dry eczema on my back, from top to bottom and I need to get rid of it in a month. Any suggestions?

No cure yet. Eczema is considered a chronic skin condition which is not curable, but treatable. It tends to get worse during dry/colder weath and better with warmer and more humid temperature. Keep skin moist, avoid excessive cleansing/scrubbing/hot bath/showers etc...Generous use of skin lotion helps. At times, topical meds/steroids, or oral medications may be needed for severe cases. Consult doc. Good luc.
Moisturizer . Intensive moisturizing may help. If this doesn't work. See your doctor for more treatment options.
