You really don’t want to mess with your Achilles tendon—tendinitis, if left untreated, can progress, even leading to a rupture. And if your Achilles tendon ruptures, you will be facing surgery and months of recovery.
The good news is, tendinitis can usually be treated with RICE: Rest, Ice, Compression, and Elevation, but it’s also very important to wear the supportive shoes, especially when doing an athletic activity like dancing on stage.
So yes, for fans, it’s pretty cool that Taylor can “Shake Off” her ankle injury, but to me, she’s just asking for more problems. Take my advice, Taylor: at 5”10, you can afford to slip on some flats and give that ankle a break while you heal!
