Thanks for this question
Have you tried steroid injections?
that would likely be the next step outside of surgery
If the tendon snaps you will still be fine and be able to sprint
what about surgery?
You could try a shock wave. Yes. HFUS
high frequency ultrasound
you would need to go private
yes I would
you would be out for 6 weeks
please don't forget a positive rating. I appreciate it
