A calf or grastrocnemius tear is a common injury and one that was new for me. It is graded 1-3 depending on the amount of muscle fibers involved. Grade 3 is a complete tear and may require surgery. I think mine was a grade 1 or 2. I decided to be my own doctor and did not have any imaging studies.
The treatment is initially ice which I placed followed by rest, elevation, and compression. The next day, the calf became very swollen and blood trickled down under the skin to the ankle and behind the knee. I have not been injured in the 6 years of running so I was pretty upset but decided to tackle the problem head on.
I had to scratch the Eagle in the Sun Triathlon which was my next race the following Sunday. Since I had been swimming , I decided to maintain my fitness and my sanity by swimming. I used a pool buoy for 3 weeks and went 3 times a week for about 30-45 min of lap swimming. I also signed up for Crossfit at the Human Lab and with the help of Jason A. my trainer I started working on upper body and core exercises. I had heard of crossfit from many people who are doing it, so I took the opportunity to try something new while I recovered. After a month, I was improving enough that I could wall normally. I got a recommendation about an excellent massage therapist Frank M. who specializes in rehabilitating athletes. I can say, he is excellent and I would recommend him highly. He has been breaking up the scar tissue (collagen) that forms at the site of the tear and this has done wonders for me. Last week, I started running again, first half a mile then 1 mile. On Sunday, my "long run" will be 4 miles. My plan is on moving up the miles very slowly and hope not to re injure the muscle. I will get massage once a week now where before I was doing twice a week. I am signed up for Rocky Raccoon 100 miler in February which may be a stretch at this point. I am hopeful, however, for The Copper Canyon 50 miler in March 2013 so we'll see how it goes.
