Postpartum question

I am 12 days postpartum. My feet are still a little swollen, my right foot especially on the top below my toes is swollen and is sore. I’ve informed my doctor the other day and she gave me some water pills like a 3 days supply which has really brought the swelling down a lot but it’s not gone.

However something else I’m dealing with is my toes, fingers, parts of my hands, right elbow just random spots on my body are super itchy. I was diagnosed with PUPPS rash while I was pregnant and it itched so bad!

The spots that itch now I can’t help but to scratch. Even though I shouldn’t, I know that but it really brings relief and feels good when I do scratch the spots.

Has anyone had this issue before? I’m not sure if it’s due to my most recent pregnancy. I did have an epidural which really made my back itch but my back doesn’t itch anymore, like I had my husband gently touching it and scratching it during labor and it felt really good. I’m not sure exactly what’s going on and I don’t want to call my doctor unless I really do have too.

If you have any advice for me I’ll take it, thank you.
