I would beg to differ on bending forward being OK. Sitting which is the flexed position held over a longer duration, and your HS stretching both cause you more pain. which would be an indication of and overall bad direction.

Lateral flex R on the other hand sounds like a possibility...try stretch out you lateral flex R. and see what impact it has on your other movements.

Good luck.

Some further information, in case that helps you work out what is happening - I have no problem bending forwards, in fact since I've been doing my hamstring stretches, I can now touch the ground without difficulty although I do sometimes get pain when I straighten up again.

My movement leaning backwards is more restricted, and does cause me pain (across my lower back, but worse on the right side)

Thanks for your continued interest
