My pain in my right Achilles tendon began as what felt like a 'popping' and then after a long run, I could literally hear and feel the 'grating' of the Achilles as I moved the foot up and down.
I was terrified as after a 20 miler, the following day I could barely walk.
I immediately went to a sports phsio who I now see three times a week.
I refuse to stop running - except for my rest day after the weekend long-un and maybe on monday when if I have pain I will do some rowing and cycling. Apart from that, I do 4 fast 10km on the treadmill (about 41min pace) per week and the long out door run at the weekend (did FLHM in 1hr29).
The physio understands that I need to run so isn't encouraging me to stop - he uses the following which definitely help:
1) Massage - of both the Achilles and the calf muscle - remember it's all connected and he found that my calf was uber tight
2) Accupuncture - I was sceptical, but it really helps stimulate blood flow to the area - this is the big problem for the Achilles, it's far from the heart and doesn't heal (excuse the pun) quickly
3) Heat and cold - and definitely after each run - 10mins each
4) Stretching - vital - and done correctly too
5) Ultra-sound with freeze gel - seems to help relax the area
All-in-all, I think that the physio basically enables me to run with some pain, but less than I had - and I must stress, the pain really only comes on during the first 15mins of any run - and then it loosens up and feels fine - and then it usually starts to tighten and become painful straight after a run and especially the next day.
A horrible injury that I hope to ditch straight after the FLM!
