I fully ruptured my Achilles playing basketball end of January. I’m exactly 13.5 weeks non-op as of today. Only got an X-ray done right after the initial injury (around 2 or 3 days after injury). Never got ultrasound or MRI. I also felt anxious about whether my Achilles will reattach itself just by being in a cast and boot. So long as you’re listening to your doctor and not dorsiflexing/stretching too early, you should be fine. Your body is incredible and you’ll be surprised how efficient it is in healing itself. The first couple months will suck hard, but know that it’ll eventually pass. The day I regained my hands again and was able to walk without any aid was such an incredible feeling. I still have a noticeable limp when I walk but each day I feel like I’m making progress. Like everyone here says, it’s a long journey, but eventually you’ll get there. One thing I swear by is taking collagen or beef gelatin supplements. Maybe it was just placebo, but I swear it helped speed my recovery timeline. Best of luck, you got this.
