Hi,

it is good that you are feeling better.

However, please listen to your body...it is telling you that extension is no good! Numbness is not a 'normal' sign for anything. It would seem to me that you are compressing the nerve root.

Any good Mackenzie therapist worth their salt will tell you that extension is not the only way to treat discs. In fact, there are 7 derangements described by Mackenzie so please don't get caught up on only one of them!

I would still think that the nerve is sensitising the piriformis...but only my opinion! L/S extension, unless you are severely overactivating your hip muscles, doesn't cause leg numbness from an overactive piriformis.

Staying within the symptom range as you are is the smart thing to do! Don't keep reassessing it! Do it once a week only. I had a patient who kept testing his L/S - he was doing it every hour or so - he didn't get better until he stopped testing his L/S!!

Good luck!
