it sounds like we have the identical problem. after 4 weeks i got it to the point where it was barely painful in the morning.
but it feels worse this week after only doing 4 mile runs on two different days on flat land with two days off in between. it only hurts significantly for about 15min in the morning. but actually right now, it is even a little tender right on the heel bone if i probe around (my pain is right where the tendon attaches to the heel bone). and I can feel it a little when i walk around throughout the day. but sometimes I forget it is there (that is what lulls me into thinking maybe its not a problem).
if i were to keep running, it would hurt for 10 to 15min in the morning, then 15 to 20, etc. basically it would get a little worse each day. that result, and my gut tells me I am re-injuring it and need to stop. i've gone back to icing and ibuprofen this week to try to minimize any damage i did by running again this week, but it doesn't seem to help too much. (maybe i have micro-tears and not really any swelling?)
i have been stretching every day, and doing push-ups and crunches. i plan to go back to pool running and stationary bike next week, although i kind of dread pool running again.
my guess right now, is that i probably won't be able to run for at least another 4 weeks, maybe even up to 8 weeks.
i don't have any magic bullet for you. basically my plan is to try to keep in shape aerobically, try not to gain too much weight, gain some flexibility by stretching, do pool running to keep my running specific muscles in shape. also, i am reading a lot of articles on the achilles tendon, and going through the threads on this website to try to educate myself.
the only thing maybe i could recommend to you is the the strassburg sock. (http://www.thesock.com/) i'm not sure if it would help you, i'm just looking into it myself. not sure if it is meant more for plantar fasciitis than achilles or if it can help both. the website says both...
i am not going to do any achilles exercises (calf raises, etc), because i am worried that i will stress the tendon and keep it from healing. i think the achilles exercises will be better for me after i am healed to try to prevent re-occurrence (or actually i am analyzing my training to see what went wrong as i think that will probably be the best bet against injuring it again)
honestly, i'm pretty depressed. i was gearing up for all these races this fall and running the best times of my life. i know that running is not everything, but its one of only a few things that helps me relieve stress and that i enjoy doing. i guess the gym will have to suffice, besides some other things.
we are taking different approaches. please give an update in a few weeks and I will do the same. i hope it works out for you. regards.
