Well, I had a hell night. A few weeks ago started having leg pain. After years of not properly stretching before exercise, my leg muscles were too short and so started the first three weeks on (intense) physical therapy. Last night, however, suddenly my calf muscles seized and formed a golf ball sized knot I could not walk or massage out.
According to the doctor, when your muscles seize, all the surrounding muscles will move in tandem and eventually go back to their original state. If the knot isn't removed by the time the surrounding muscles relax, the muscles will tear.
My doctor doesn't know how bad the tearing is because, at present, my calf is swollen to almost the thickness of my quads and he tells me I have six to eight weeks of immobility in my near future.
On the bright side, I finally figured out what to do with all the throw and decorative pillows all over my bed.
