Injury Advice Please

[Sweder]

First up, welcome to the forum
We're a pretty patched-up bunch so someone may well pop up with advice based on a similar problem.
If they don't:

Your left achillies/ right calf combo suggests some form of compensation in your running action. A chap I run with at weekends developed trouble in one leg, finally biting the bullet and going to see a physio. His doc pointed out that the good leg had developed considerably more muscle than the injured one, indicating a compensatory action.

Get youself to a sports physio and take your shoes.
Anything else would be taking blind advice, and could make things worse.
Good luck, and please let us know how you get on.
