Thanks ice, and everyone else who has commented advice, always much appreciated.
To detail the issues, I over did it, the pain that remains appears to be localised to 2" off centre from my spine and 2" above my waist on the right hand side of my back.
After visiting the physio no damage was located, but a few points were noted. I have anterior pelvic tilt, the left side of my lower back is quite a bit more developed then my right (this is where the pain is, and was pointed out before I advised where the pain was), possibly caused by years bad seating habits.
I have a very stiff pelvis, and I have very poor flexibility in my ankles. My erectors are also quite developed as well in comparison to the rest of my lower back and are very pronounced when I bend over, this is not an issue and not a source of pain.
On a posative note, my hamstring flexibility is not as bad as I thought it was, so my stretching of them has been working
Since the physio visit (21st jan) I have been consistently been doing soft tissue work every night (time in front of the tv has never been so productive), specific focus has been on my lower back, glutes, and hammies. I have been doing regular (at least every other day) hip flossing with my green band, and ankle stretches with the same band.
I have added in some oblique twists at the gym at the end of every session keeping my core locked, I have also been doing the aggressive ppt reverse crunch with leg extension every night, and occasionally thrown in a few planks as well.
I have been focusing on avoiding apt in all my lift movements and been working on keeping the core tight as well, especially while weights are low.
So i would like to think that i have been doing the correct thing already?
I didn't think SLDL's were the best and only solution. It was more a case of they seem to be another tool I can use in my rehab tool box. However if they are just more a cause for concern and I am at risk of doing further injury then I will ditch them.
