Peroneal dislocation

About two years ago I had an accident with my horse and sprained my ankle badly.  (She ran me down).  I saw my PCP a couple of days after and he said to use the RICE method of treatment, and sent me for x-rays to be careful.  (no break)

 I followed the advice and was able to participate in a tri a couple of months later with little to no pain.  I did notice however, that the bone on the side of my ankle hurt when I pressed on it, and wearing boots and my running shoes still hurts because it hits that area.

The pain has now come back in a serious way, and it runs up the side of my leg (on the outside).  There is no swelling.  Turning my ankle up and out causes the most intense pain.

 I don't want to schedule an appt. with an ortho if it's something I can take care of myself with massage, stretching, ect.  Should I try the RICE method again, or should I look into finding a doctor to help me out?  I'm not sure if it's common to have pain this late after an injury. 

Thanks for any help.
