Hi..
I read your problem.. For me it appears to be radiating down from your low back area....
If I were your treating doctor...
I would advise you to have a
MRI done for your low back especially your Lumbar region...to rule out any disc pathology and facet joint irritation....
I would also advise you to...
Avoid sitting for long time as this would worsen your symptoms and source of pain ..
Don't lift ant weights..
Avoid forward bending...if needed use your knees to reach floor than your back...
Lot of icing on your back....
Back extension like cobra stretches frequently... like 10 reps for every hour....
Lot of core stability
Lots of glute stability....
These things will definitely bring your pain down and make things comfortable...
you can slowly resume your activities... once strength pitch in.... which you know in your normal activities....
Hope this is helpful for you...
Kindly revert back incase you need any further clarification.....
