Hello and thankyou for approaching DoctorSpring with your query.
I have gone through your case and understand your concern. I have taken a look at your MRI report an I don't think surgery is an absolute indication at present. Nothing is so bad that you have to get scared. You can definitely try another session of physical therapy.
Surgery is an option only if you fail conservative treatment. Surgery is not required as an emergency right now.
I hope this has answered your question.
Please feel free to follow up with further queries.
