Itchy rash near chemo port—normal or concerning?

I have a red, itchy rash on my right neck, just above chemo port. I'm being treated with docetaxel plus cyclophosphamide oct 19 and recently had chemo port surgery oct 17. I also had a mild fever, general pain, and appetite decreased since Oct 22. Doctor prescribed betamethasone. I'd love to hear from others who have been through something similar. - Have you had an itchy rash on your neck or chest during chemo or around port placement? What was it like for you? - Did you notice any other changes, like a fever, at the same time? Thank you for sharing your experiences and any tips that worked for you.
