Have been continuning to make steady progress as I gear myself up to enrol for a ParkRun. Then on Friday morning as I was running along I felt what I can only describe as a gentle thwack across the back of my calf. Thought that a twig or something had bounced up and hit me ... no big deal ..... but then awful pain. I had to limp back home and quickly stuck some ice on it but then had to go to work where I limped everywhere. Yesterday I could walk ok (well, a bit like John Wayne and after a couple of ibuprofen) but going down stairs is agony. Today pretty much the same. Running seems out of the question - but for how long? Anyone else had anything similar?
