Achilles rupture week 6 post op , hard cast, radiologist and Surgeon disagree on rerupture

Going to try and keep this as minimal as possible. Achilles rupture. Hard cast for 6 weeks.

April 3 - Ruptured Right achilles tendon, basketball, knew it instantly. I have torn the left achilles (this time, the right one). Had surgery on the left one, came back stronger all good. Felt it would be the same this time around. Wrong.

Week 6 post op, in hard cast, I stretched involuntarily. Felt a pop. Literally was just laying in bed, on my back, leg propped up, in a hard cast. Pandiculation; the forced body yawn. No pressure, no fall, just a POP. I freaked.

My Surgeon orders an MRI. I go and take the MRI. Radiologist say "Full achilles rupture 2-2.5cm in length." My surgeons response, verbatim "he is fine, stay the course." I call my doctor, and the nurse tells me to trust the surgeon. I have an appointment with him tomorrow to understand what this means, and why he disagrees with the radiologist.
