My bodily operating system, that I call Jennifer, is not all it should be, either.
I've had Achilles Tendonitis for a while and noticed that not only was it not healing but I'd developed large lumps on tendon. It's scar tissue. I've re-injured the tendon so many times and so frequently, it doesn't heal. So it's R.I.C.E. and, if the doctor gets his way, cortizone shots followed by an immobolizing cast. Not a fan of immobility at any junction, I find winter to be a particularly bad time to be casted.
If anyone has crutches and a spare computer, send them my way. I will kow tow in your direction twice a day for at least a week.
