Itching and skin dryness

Iv

So it’s been 3 weeks now since I had my baby but I’ve been itching . After bathing my skin, eyes,nose,ear, tongue, throat itches and the skin dryness is out of this world . I did a little research and found out that flagyl was the issue or so I thought. I stopped taking flagyl and it has reduced a great deal but once it’s morning it gets really bad then calms down later . Has anyone experienced this? What did u do to help with yours ?
