He is no longer taking chemo nor radiation & hasn't for the past 6 mos; was told to stop his diabetic meds-pill form as there was no need. His feet & ankles have been terribly swollen for 3 wks, he can barely wear shoes when needed. Hospice & oncologist have not offered a suggestion. His salt has been cut back to zilch, soaked in epsom salts, & he's poured rubbing alcohol on his ankles to no avail. Any suggestions?
