I have been going to the gym for close to four years, but have been fairly injury-free. Today I was finishing up 35 minute walk and run on the treadmill and I wanted to pick up the towel that fell and moved the back of the treadmill. This was when I changed the pace from 5 miles per hour to 3 miles, so I thought I could get on it just fine. Instead I tripped on it and hit my left leg pretty hard. A little lower than knee. When I looked in a couple of minutes, it was so blue and so swollen that I have never seen anything like that on myself. Nevertheless, I did everything for Day B (chest and leg) including steam bath! It actually hurts without touching, so I activated ice machine and applying ice. Some websearch told me that I have to apply ice 20 minutes on and 20 minutes off. Also taking ibuprofen pills doesn't sound like a good idea. Tomorrow being Day C, cardio and ab, I was hoping to run for 45 minutes. I hope I don't end up resting tomorrow because of this. That's OK, right???
