Thanks for the quick reply.

I just want to say since my first post I have consistently been stretching the Erector Spinae, and I can say I do not get the intense muscle pain either side of the spine 3 inches up from the waistline as stated in my first post in the middle of the night from lying on my front... Ive only just thought about it, and im really pleased with that.... Another technique Ive started doing to help me is - when I really feel the urge to lie on my front I place a thin flat pillow under my hips and pelvis to stop it sinking and this also helps. So my next step is to try a swim out which is something I havnt done for a long time prior to me starting this thread.

Moving on.
my back is still very delicate at the waistline centre by the spine in the night if get up for the loo and I still get the sharp knife like pain on the right side when I wake in the morning and i have to be very carefull when picking my baby out of the cot... I can CONFIRM this pain and delicateness is GONE within half an hour of mobility around the house... Which suggests to me its definately to do with Lumbar disc/facets.... as I understand they close together when you lie down at night and then open back up when you are mobile in the day,... So if there are signs of degeneration of the facets and disc then this will be exacerbated when I first wake up..

Theres also the sharp pain I talk about far right side at the waistline which comes after a physical days graft. (mainly when my hips are flexing and extending continuously throughout the day especially if im carrying heavy weights.) - could this possibly be from the hip dysfunction.?

Can I ask would the above x-rays show a hip or sacroiliac dysfunction?

Would jogging on a treadmill also aggravate the discs and facets?

Thanks
