Thanks people for your comments. I'm fine. A couple of snarling unwelcome days, but things are getting resolved.
And in running news 14.25miles on road and path in just under 1hr53. Cold and wet out. My right heal is still tender. Main concern was my left hamstring. It was getting very tight and I had to slow a few times to settle it down. Could have been the cold (went for shorts instead of usual winter tights), or my heal knocking my running out slightly which effected it. It was a day of wrong turns so took a few unexplored streets. Managed to find my bearings again though.
