Try some KT tape or Kinesio tape. I strained my achilles tendon on the side of my foot and I taped it immediately ( I do therapy). I had no pain, full function, slight tenderness on palpation, and healed far quicker than not using it.
Because of its location, you can do it yourself (the taping). You Tube videos out there show the way to do it. It's a special tape, can stay on for 5 days, ok with showers/bath. Supports the tissue healing at the same time provides some pain relief and support. Many of the olympic athletes were shown on tv wearing all the various colors. NB the colors do not have any meaning as to strength, etc. its just a color. Just my .02 cents.
