Hi Connie,

Sad to hear this but not surprised.   I suspect with there still being some blockage the toxins build up in her system and make her sick.  Puking helps to cleanse her out, but leaves her weak.  If only they could work on helping her get strong enough to operate on, they might be able to do something about the blockage.  Have you tried checking with other Vets?  It never hurts to get a second and third opinion.  One might view the situation hopeless while another, perhaps having had some personal experience or wind of new treatment, might have a course of action.
