Hi,
Thank you for posting your query.
I can understand your concern about your condition, as you have not been able to consult your neurosurgeon.
First of all, let me reassure you that there is no need to get concerned about these findings.
The decision to surgery depends on the symptoms. If you have 
severe leg pain, which does not get better with medications and 
physiotherapy, then, operation may be needed.
Medications helpful to relieve the 
nerve pain are 
pregabalin and 
gabapentin capsules. 
Physiotherapy includes IFT, ultrasound and back extension exercises.
The choice of surgery can be made after seeing you and your MRI reports.
I hope my answer helps. Please get back if you have any follow up queries or if you require any additional information.
Wishing you good health,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
Senior Consultant Neurologist
