I don't know anything about alternative medicine for scleroderma--and have to admit skepticism about  mushrooms--but I will look for info and evidence of effectiveness. Might take longer than usual for this hunt.
Sounds like the docs are on the fluid retention issue. One of the previous articles on IV feeding during dialysis says that "usual indices of nutritional assessment--body weight...etc.--may be inaccurate in patients with end-stage renal disease, as the results are often skewed by fluid retention." ("End-stage" only means the patient is likely to need dialysis consistently in the future.) Still, 61.2 kg = 135 pounds, so Bill is apparently gaining some real weight in addition to the fluid. I'll see if I can find any general info about why fluid retention is common in dialysis patients.

Congratulations to Bill on the full hour in a chair! It must have been so hard to do. Hope the hypnotist and pain team can help with the toe pain.
