Dear Elvster (Mike)
Recovery from Discitis generally can take up to year or more, so the advice from your consultant is sensible. However, if you are clear of the initial infection and inflammation has subsided significantly my guess is that you have several structures in your spine area that are suffering from multiple adhesion sites. It is not uncommon to have stenosis occurring on several sites post a disc infection. This can present with chronic pain for a very long time.
You may want to visit an MSk physio such as yourself for a detailed assessment to start gentle exercises to improve range and improve core stability. because of the herniated disc that you have, I might want to improve extension first. I might also want to improve lumbopelvic ryhthm. Knee rocks within pain limits maaybe helpful..this will help open up the stenotic areas . BUt this has to be done gradually.
You should be able to start your stability exercises in neutral first. Lying on your back, maintaining a good core(flattening spine) and perhaps adding heel slides and upper limb elevation. and or lower limb abductions...
this can be progresses graduallyin sitting, standing...use of light weights
if your pelvis is not moving effectively anymore due to these multiple adhesive sites, then the strain would be on your spine when you flex, for good forward flexion, at least half of the movement shoulde be coming from the hips first before the back takes over...this is something you can work on with your physio...
hip flexion in supine lying, maintaining a pelvic tilt and gradually stretching on a gym ball may be helpful...
when you start your exercises, you may be feel an increase of symptoms( by which I mean pain alone) this does not mean anything is significantly wrong as your infection has been controlled...however this pain should gradually lessen...you may want to consider pain control in addition with any vexercises you start...
As you know, any neuro symptoms seen would be the concern...not necessarily pain...if you are not experiencing any neuro signs (bladder issues, gross muscle weakness, parasthesia etc) i wont be concerned and should think you can start your physiotherapy...
The reality is even without any physiotherapy as you continue with your regular daily actvities your pain should generally subside...
My advice is visit a physiotherapist, get assessed and start an exercise program that is aimed at improving range and corestability...
Good luck
lots of soft tissue work will be helpful...
