I would approach this from the following perspective: Do you trust your physiotherapist? Or are you just unhappy that her recommendation is you should stay off the bike for a while?
Even if I had a background in physiotherapy or orthopedics (which I absolutely do not!), I could not judge your case.
If I had to make that decision, I’d likely err on the side of caution and put the energy I’d normally invest into training into recovery and physio instead.
