Dupixent a week later

Hi all,

Took my loading dose of dupixent 5 days ago. Still very early obviously. I noticed that I was far less itchy for the first few days, and my skin is clearing already on my neck and arms which are my problem areas. Much smoother, not broken, pink instead of red. However, I felt pretty itchy last night all of a sudden, and my skin feels like it’s tight and dry. Kinda like it’s healing. I don’t know if it’s the healing that’s causing this sudden itch again. I’m not scratching until I bleed, and it’s definately not as violent an itch as before. Just wondering if people had this experience? Did itch come and go like this for a while whilst on dupixent?
