Shout and BO oddity

[HeLRaZR]

I noticed this soon after I got BO at level 24. At first it was odd now its downright perplexing. My habit is to shout then BO myself. What happens is that while the BO swirl at my feet is active, My bowls are full. When it changes to the Shout swirl at my feet, my mana bowl drops by 1/2 and I lose 30 HP's. When the BO swirl comes back my bowls recharge. As soon as the Shout animation starts again, my HP and mana bowls drop by the exact same amounts and then stay there. I can drink a pot but generally as soon as the bowls refill they go back down. Finally what I have found is none of the healer NPC's will heal me....???
