Suggest Treatment For Plantar Fasciitis

Ihave had plantarfisciatis for two and a half months now and alot of inflamation. I have followed through on everything that was recommended such as phio--accupuncture--massage--hot and cold compresses as well as stretching. Nothing has worked and now they tell me there s nothing more that they can do, yet I am in pain and have to rely on pain killers to ease the symptoms which have given me nausea now.
