My daughter has been struggling with lower pfts for months and we finally had a bronch which turned nothing up except a bit of staph and roto virus. The docs think the roto virus has just been wrecking havoc but that there's nothing to do but hope it clears up. Has anyone else dealt with this particular issue? There's not treatment since its a virus- except for lots of cpt, hs and pulmozyme. Any BTDT out there? Thanks.
