Pain That Only I Saw...

An AU set after Season 3 Episode 16, but with a twist that started from the end of Episode 15! I do not own The Flash or any pictures used, and it is a Snowbarry/Flashfrost based story.
"Ever since Barry's fight with Savitar, were Savitar stabbed Barry with his dagger through the shoulder: Caitlin has noticed that Barry has been acting differently lately, and that his injuries seem to get worse as time goes on...and it worries not only her, but her icy alter ego as well! And the worst part is that nobody seemingly cares but them other than Cisco! Can Caitlin find out what is wrong with Barry? Can she be there for him when she finds out the truth? And will they find out how much the timeline has changed?"
