First I would mention that ice is no longer recommended for this type of injury, while it reduces inflammation, it slows healing and the removal of wastes in damaged tissue. This type of injury responds best to immediate treatment, it is unclear how well it will respond 1.5 yers after the trauma. I would use H & A’s compound arnica oil 2x per day with heat, Physical therapy, internally 2 parts Teasel root, 2 parts Achyranthes/Huai Nui Xi, 1/2 part Horse Chestnut, 2 parts Goji Berry. Without more details I cannot be more specific than that.
