just not able to do this. I am able to do wheel, etc. My teacher tells me that my wrists are not too strong, it hurts in my elbows when i am doing this. i am able to lift my legs up etc. do it with the help of a wall. But i am not able to retain the position. I feel like the entire body may invert and my neck will be sprained. How do i overcome this fear...
?

With fibromyalgia you would want to be kind on your neck. Instead of shoulderstand, try legs-up-the-wall pose (a variation on viparita karina) in which you lie on a blanket with straight legs stretched to a wall mearby.

I stayed in this pose for 30 sec the first day and 1,5 min the second day. The thirda day I woke up with a migraine which lasted 4 days - why do you think this happened? I am on bio-identical hormones for menopause and was wondering if this could have anything to do with it?

Hi Devapriya - a good practice to get into is to keep the chin away from the chest. This has the effect of creating space in the front of the neck to facilitate easier breathing and also activates Jalandara Bandha (Tha) - protecting the back of the neck. An instructor should be able to slide a couple of fingers just behind the neck.

Hey Devapriya from PA,

I'm not a bodybuilder, just a regular girl who had tons of trouble with this pose in the beginning. What you need to do is practice many spinal twists and open up the thoracic are of the spine... ie. the upper back and between the shoulders. Focus on these areas for an hour long practice. Then when you're ready to go for it, make sure to have your chin tucked in close to your neck, as though you want to make a double chin....this way your air flow wont be restricted. Let me know if this helps!
