Just a side note on the fish oil intake. My brother recently suffered a cut achilles (piece of metal fell it and sliced it up. They originally thought it was 75% cut, then 50, but a third opinion was it was about 33% detatched. They told him to expect about 2 months on crutches, because surgery was not needed. I told him to take some chondroitin (1500 mg maybe) and fish oil (GNC tabs, about 20 a day).
2 1/2 weeks later, he was off the crutches and able to walk around in the medical boot. They had him on heel lifts and he's been able to take out almost all of them (4 or 5).
I've reasoned that maybe the achilles wasn't completely cut as much as they thought, or he just heals very quickly, but part of me cannot deny that these supplements made a huge difference (2 - 3 months vs 3 1/2 - 4 weeks to talk out all the heel lifts is a lot.)
