If that were me, I would hit the ER and fast! For it would be a sign,
for me now, that I had clots in my knee and leg.

I would not let them give me aspirin or anti clotting meds. They are
actually worse than the health problem. Taking vitamin E capsules for
myself only. I would take 2,000iu a day. I don't remember what the
average dose is, but I am way over average size. I would also keep the
leg elevated above the heart, as much as possible. Something else that I
do here, is to rub in creams, lotions or the like with vitamin E oils in
them or alone. I vary what I do for the rub. Even to just massaging the
knee and leg as much as possible.

One other thing to consider. Are you breathing harder or panting, with
the same amount of exercise?

Now, since I scared you, as I was, when first diagnosed with blood clots
in my leg and lungs. I'm wondering if you might have an embolism in the
knee. My cousin was just operated on for that, in his knee. Also, you
might have been stung by something. hey, ever know.

Now, I am not trying to scare you, but trying to educate you about what
might have happened. So if you have health insurance or can otherwise
get treated. You might want to hobble into the docs office or ER and get
checked out. Chances are, they will order an Ultrasound of your leg and
knee, maybe even a CT scan or MRI. Better safe than sorry. At least then
they could maybe eliminate what is wrong. I'm hoping you just twisted
the knee somehow, when you weren't aware of it. For they don't always
manifest themselves, for awhile.

Again, I only said what happened to my cousin and myself above. I am not
prescribing any course of action or meds.
