text: regarding yoga: any inofmation on the plough position? i have begun a yoga schedual, on my own, as i am a student and cannot pay for a trainer, but i am moving along quite nicely. although, i do run inot difficulties when i complete my transition into the full *plough*. after i release the pose, i find myself with a terrile headache for the next 2 days. this has happened frequently. anyone have any ideas? this is not a good sign. something is wrong for sure, but from your description i cannot tell what it is. i'd strongly recommend you to do either of the below: 1. find a good teacher and show him/ her how you do the pose for diagnosis 2. if you cannot afford #1, stop doing the pose  #1 is preferred to #2 if you can afford.  if you intend to continue learning on your own, remember this: despite all the potential benefits of yoga, it can also do harm if not careful.
