I had blood clots in my heart 4 years ago. shyt is no joke. You have to be on blood thinners for the rest of your life, take care of your body, and go on a diet, etc. You have to draw your blood, like every month or every week depending on INR test results.
I'm good now. In late 2000, my legs were swollen, and I gained weight every day, like gaining 5 pounds each day, my weight was over 235 pounds and, when I coughed blood coming out of my mouth, short of breath, etc. Now, I weight 160 pounds. Go to the gym 3 or 4 times a week.
