Yoga is supposed to be good for your back right!?

Laura

Okay so I’ve heard how amazing yoga is and fixes a whole bunch of problems including back pain, I don’t have back pain but since doing yoga after certain poses my spine feels uncomfortable like all the vertebrae have been stretched out.... getting and being in said poses don’t feel like too much strain at all until I come out of them .... my question is, is this good uncomfortable feeling and does anyone else get this? x
