See my post No 32.
The short-term injections a clot patient has to self-administer are called Lovenox (Enoxaparin Sodium).
A deep vein thrombosis, or DVT (blood clot in the leg) is nothing to mess around with or to try and self-medicate. If a person is having any of the symptoms-—calf pain, redness, swelling-—immediate medical attention is required. The blood-thinning pills take about a week to kick in, which is why the shots are necessary in the meantime.
Also, trying to thin your blood on your own is extremely risky. You might not thin it enough, resulting in death from the clot, or you might thin it too much, resulting in death from bleeding. You would have no way of knowing. Just don’t try it.
These clots can break off quickly and with no warning, and they can kill. They don’t result in strokes or heart attacks-—they go to the lungs and cause pulmonary embolism.
