The doctor is very fond of giving her antibiotics at the slightest hints of infections (I'm sure he would not accept that honey prevents infections, as I have found it to). She dislikes yogurt and although antibiotics destroy vitamin B as well as the gut flora she takes so many pills already that I hesitate to suggest anything else. For the same reason I have not suggested herbal circulation tablets.Her diet is not very good, as the food is provided in the sheltered accommodation, but she makes healthy choices where possible.

Run, don't walk, to see her doctor and ask for a list of all the medications she is being prescribed. It is highly likely that her persistent leg ulcers are being caused by an NSAID, since they inhibit healing in ways we don't really understand. If she is being given an NSAID, have her request to be taken off it and switched to simple enteric coated aspirin. Better yet, if finances permit, have her checked out by a clinical ecologist who may be able to locate her allergies and the source of the rheumatoid arthritis, even at her age. Editor.
