Great case, Alan.
I'm taking notes re the tincture mixture you mentioned.
I was also working with a man recently who had final stage pancreatic cancer [as you know], and he had terrible, painful swelling [oedema] of the legs, genitalia and abdomen [this is common in late-stage pancreatic cancer]. Arsenicum 30c [homeopathic] was able to bring the swelling down where diuretic medications hadn't succeeded. It also helped with burning pain in his chest, acid reflux and his respiratory problems. His doctor also sat and watched as he took magnesium phos [CM homeopathic potency] for pain and clearly was relieved.
Many doctors are supportive of homeopathy, but there is a mythical expectation that homeopaths and doctors are opposed.

Keep up the good work.
