Itching/burning skin with scleroderma

Hello, I am wondering about how others handle the itching/burning skin of morphea/scleroderma. It seems that if I get too warm, wear anything except very soft, loose clothes, and most foods ( except apples) triggers the itching and burning skin and activates new plaques. I started on Gabapentin 100mgdaily, increased to 100mg twice a day. This has helped some, but it has also causing some ankle swelling. I used clobetasol or hydrocortisone crème twice a day, Jojoba oil, only tepid showers . Benadryl causes anxiety for me, so that is out. Claritin didn’t help. Has anything worked for you?
Thank you 🙏
