The problem is that you have to find remedies that is not affecting CNS, and often use local treatment:
An onitment from Germany: ARNIKA SALBE, is good for problems as arthritis. In Germany and Norway it is not by presciption, but only sold in pharmacy.
I Suppose you know about IBUMETIN GEL AND ORUDIS GEL, both gel to use loccally, and be carefull ith NSAID oral taken (too high dose and bleeding complication).
We have had some pt. who has responded good by massage, thouch therapy, foot-care: warm water, and massage to the feet.
If your workplace has volontairs; they can learn simple tricks from the physioterapist and get supervision from you (maybe pt us marevan, has H blood pressure, diabetes and something like that.)
I hope this was some advice
