Dumb heel and/or ankle!

It does sound like localized achilles inflammation. Which brings us back to the search for the cause. Could be alignment (see Knott's post above), I would suggest going for a deep tissue massage to make sure there aren't any nasty trigger points in your calf that need to be worked out.

If you're thinking about it I'd go with the starter set.

Is there any possibility of direct pressure on that part of the tendon causing swelling? If that's the case, it needs to be relieved.

Keep posting and let us know haw you're doing.
