Good luck. This injury is frustrating.
I think I read almost every Achilles injury thread on this forum when I had it bad. Doing glute strengthening and getting ART done on my calf / Achilles helped get me out of the rut. I’m surprised glute and core work hasn’t been mentioned on this thread yet. I had a gait analysis done and they basically told me my core and hip / glutes were very weak. Make sure your feet aren’t crossing the midline when you land. This is indicative of weak core. I also increased my cadence, which was super low at 160spm to low mid 170s.
I make sure to do a few glute exercises before running. I feel them engaging while runny and I believe it takes some of the strain off of the calf complex. I would also make sure you don’t have an exaggerated forefoot strike.
I’m hesitant to say I’m fixed because it still flares every now and then. Hell, I made my own thread on this a few weeks ago lol. But currently it doesn’t bother me in the morning or when I’m running.
pay close attention to it. If it feels like it’s getting worse 24 hours after exercise, stop running. Heat it before runs, ice after. Make sure you thoroughly warm up, especially if you prefer morning runs. I like to do the drops before and after running. Gradually increase resistance (weight) as you feel better.
Others might disagree, but wearing a shoe with a high heel offset also helped me. I alternate a 5mm with a 10mm shoe now. Any lower than that I really feel it. Tried altras for the wide toe box and it set me back after I thought I was healed. Lol.
Also agree with the poster who said do ankle alphabet before the first step out of bed.
This minor essay is basically my own experience. Yours might be different. Find what helps you.
