I've been walking a lot recently. In my normal day, I'll walk to work (3 miles), during my lunch break (2 miles), and home from work (3 miles). I've been doing this on and off for the last month or so, only taking breaks during the weekend or in the case of rain. About a month ago I got new exercise sneakers and they're AMAZING. Very light, very nice for walking.
On Sunday, however, I noticed some pain in the back of my ankles. I didn't walk at all on Sunday; I took a short (3 mile round-trip) walk on Saturday. I wore new shoes Friday and Saturday night, but otherwise didn't do anything out of the ordinary.
Yesterday I used some new sneakers again, but even before I began to walk in the morning I noticed my ankles were incredibly painful. The pain died down a bit as I walked on, but when I took my afternoon and evening walks, I noticed it again. It was especially noticeable when going up or down stairs.
Today I switched back to my normal exercise shoes and did the same. Same result: the backs of my ankles hurt like crazy in the morning; the pain lessened as I walked more, and it returned and was extremely painful when going down the stairs at lunch. After looking online, I believe it might be Achilles tendonitis, which matches all of my ailments but is much more common in older folks (I'm only 25).
Just sitting in my chair I don't feel anything wrong; however, I can find the source of the pain about an inch or two above my heel, around the Achilles tendon in that area. I've massaged the area for a good 10 minutes and it feels a lot better (it no longer hurts when I massage it), but I'm left wondering "what the hell did I do?" Again, I've been walking for the past month or so with no ill effects, using the same shoes except for yesterday; but my ankles already hurt before I started yesterday morning. I didn't do any extreme working out on Sunday.
Anyone have some ideas for where this could have come from, or what else I can do for it? And if it'll go away?
