Just in case someone is reading who only has a sore Achilles tendon, I had a sore Achilles tendon before this happened.
I played volleyball weekly, if not daily from ages 12- 28. Then I had kids. Running and yoga were my main workouts with occasional tennis and biking. I picked up a volleyball again at 38 when my daughter started playing. A 10 year break! I didn’t start playing regularly until a couple months ago. I joined a rec team with a group of excellent players who all played in college and are quite a bit younger than me. In my volleyball lapse, I forgot how much of a workout it really is. Not wanting to forgo my workout routine, I continued my workouts/runs on the game days thinking of them as a warm up. I think that’s what did me in. What I thought were sore calf muscles were, I believe, Achilles tendons that were telling me to chill out. A busy travel/work schedule the two weeks preceding my injury led me to workout extra hard on the days I was home. I did a quick hill run the Saturday before which I read is not a good thing to do if you have a strained Achilles.
Could it have been prevented? I don’t know. My doctor thinks not. I eat only organic produce, grass fed meat, wild fish, etc. lots of veggies and nuts, nothing packaged. I drink a glass or two of wine most evenings. I don’t take any medication - not even Advil. I have always exercised regularly but not obsessively, 4-7 days per weeks my entire life. I am 5′11 14o pounds and have been (give or take a few #s) my entire adult life. I am of average build but I do have thin ankles. Does that have anything to do with it? I guess things just wear out.
