Slight back pain when in bed (caused by yoga?)

Yoga Discussion General Yoga
#1

Hi, I have noticed that if I do yoga (I do ashtanga) the next day, in the morning I have slight back pain when lying on my back. It in the lower back and it feels like it's caused by the curve in my spine straightening and laying flat on the bed.

I don't get any pain or discomfort while I'm actually doing yoga, but it must be connected since they correlate with each other.

Does anyone have any knowledge about this particular type of lower back pain (it's only slight pain), how and why it's caused etc.

Thank you

I can't ground through my sitbones

If it ihappens every time you practice then yes it is related with your practice. You need to fix your back first by therapy yoga approach before trying Ashtang Yoga.
