First time Shamanic Breathing practise questions.

[Devansh Saharan]

Everything set up as said.

Started, after about 5-7 minutes I started having a lot of tingling in my hands, by 10 minutes I had severe pain and tension in both my arms(particularly in wrist and palm) . But I continued till like 20 min when I could no longer bear the pain. It took 10 minutes for the pain to fade and about an hour for me to return to normal motion, my hands were trembling a lot. 

Same thing happened today. 

Is there something I can try? 

Also I've been reading about hyperventilation and how it stops blood flow to brain, is there anything to worry about?

I haven't tried shamanic breathing because I am worried about hyperventilation and potential brain damage. Did not do any extensive research though. Would like to hear from people who might know more.

As for your problem I can't really give you any advice as I haven't tried it, but I think it is wise not to go beyond the point of strong bodily pain in any spiritual practice, at least in the beginning.

Same here. sometimes I wanna give it a try, but I'm too afraid to make a lengthy like 20 minutes!
