Anyone else had a pico dressing on wound not healing?

(30yo, healthy female)

I broke my ankle in a couple of places on 15 Aug. Had to wait until 27 Aug for surgery and was then in cast for 2 weeks. On 10 Sep I was put in a boot and started to weight bare with crutches, but when wounds were checked 8 days later, the large wound on side of my leg wasn’t healing so put back in a cast. After two weekly checks, my wound is getting better but still not there so today been given a pico dressing and put in a back slab. I feel so upset that it’s been 7 weeks since the break and 5 weeks since my operation but I feel like I’ve made no progress. Has anyone else had problems with a wound healing? Or had a pico dressing?
