MRI Scan Showed Central Protrusion Butting The Thecal Sac. How Long Wil This Last And How Severe Is Injury?

I have a 2mm central focal protrusion butting the fecal sac L5 S1. Originally it was an 8mm anular tear with no nerve impingment. about four months ago I started feeling pain in my legs mostly the right. Long story short i recently had an mri that showed the 2mm central protrusion butting the thecal sac and I guess thats the reason for the sudden siatica in my legs. My Dr mentioned that the tear was getting smaller but I have had symptoms in my legs foe four months now, I'm doing PT and I think I'm making progress but I just cant seem heal completely. How long should this last and how severe is this disc injury?

Hello,

Even though the size of the intervertebral disc prolapse as reduced from 8mm to 2mm, It is the decrease in the intervertebral space which may create the problem.

You should understand that intervertebral disc is a structure that acts as a sponge and shock absorber.
When this gets injured the intervertebral disc space decreases and degenerative bony changes happens.
