You asked: i have tumors on both adrenals (2.6 and 2.8) could this cause edema. is those large tumors? only low on salt all other blood work ok.

No: The size of your tumor are not large enough to recommend surgery without them producing too much hormones. You say salt is low, have the adrenal hormone levels been checked as this can be a sign of hormone deficiency. First to eval adrenal nodules besides size is if they are making hormone so get cortisol, aldosterone and talk to doctor about checking for pheochromocytoma (rare adrenal tumor).
