After this came two years of being troubled by injuries in both 2016 and 2017, with a back stress fracture and an ankle surgery. Kellys first major test of overcoming this type of setback proved to be successful, bouncing back to  have an exceptional 2018 becoming British All-Around Champion, British Bars Champion, winning Commonwealth Silver and Bronze medals, and making individual European and World Championship finals.

The following year continued a similar trend until the beam routine that secured Kelly the All-Around Silver at the British Championships was found to have been performed on three fractured metatarsals which she injured in the final apparatus warm up, and therefore had to forfeit the apparatus finals and the European Championships she had been previously selected for.

 One COVID lockdown and a shoulder surgery later to repair a torn rotator cuff tendon, Kelly was shown to fight her way back once again in 2022 with new routines to help team England secure team Gold at her third Commonwealth Games in front of a home crowd in Birmingham.
