My eczema is getting out of control, and spreading

hi, my eczema is flaring up so bad, it's so itchy, it's on my calves, it's on my forearms, it's on my inner thighs, and under my thighs, and on my waist, and it's also in my hand now. idk what to do, and im scared to use my , hydrocortisone, because there's so much eczema, and I only use the hydrocortisone when I have a small patch and try to catch i. Its so so itchy
