Went to the hospital emergency room yesterday afternoon. I had been having light headed spells and a sore right leg which it (and the foot) started to swell. Well, they found a blood clot beneath my knee. I had the option of outpatient treatment but the lightheadedness had me anxious. Today they did a CAT scan. They found clots in my lungs which is why they think I was feeling light headed. Wish me well.
