bluebug,
I would recommend an arnica cream - something like Traumeel. Traumeel gave me my life back and helped me walk again pain-free (I had heel spurs in both feet)!! It is a homeopathic cream (so
no Corticosteroids side-effects), it's a natural product from Germany. It is used for injuries of all kinds (sports, accidents) such as sprains, dislocations, contusions, effusions of blood and effusions into a joint, fractures, etc; inflammatory processes and degenerative processes associated with inflammation on the various organs and tissues (e.g. periodontitis, suppuration of the gingival pockets, periodontosis), including, in particular, on the support and mobility apparatus (tendovaginitis, bursitis, scapulohumeral periarthritis); arthrosis of the hip, knee and small joints.
Here is a link for the company's Mexican affiliates:

Hope you find relief.
