Day 6 after my 5 mile time trial and the slight twinge that came out of the blue below my Achilles has increased in mysteriousness. At first I thought it was a recurrence of my posterior tibialis tendinitis but this injury I originally had in my right leg, not in my left.
Secondly, I had not run much going into Wednesday, as I had been laid low with the flu for a week and in general my mileage had been moderate for several weeks. Finally, there were no warning signs, no previous stiffness. In fact, just the week previous I had been delighted at how painfree both my calves were after the constant problems, especially on uphills, of 2010.
I ran only once in the last six days and have attempted to pinpoint different patterns. Touching, overstretching and walking on the leg seems to increase the soreness of the area. At first I thought it was on the sides, but closer inspection has revealed the sorest spot is right at the lowest spot of the Achilles tendon although it moves slightly.
Readings on the internet suggests this could be a strange injury called retrocalcaneal bursitis. It was not easy to come to this conclusion but it is the fluid sack behind the Achilles tendon just where it attaches to the heel bone. This is consistent with the location of the soreness. I can move up on my toes without problems but walking uphill or running causes immediate pain. Posterior tibialis caused pain on uphill, downhill, and during normal walking and locked my ankle when attempting to step up on my toes. So there seems to be subtle differences. I am torn between trying to get an appointment with John or chancing a quick x-ray at the Beacon Clinic tomorrow to confirm.
My planned Scarr race is definitely gone meaning I did not get any hill running under belt as I had planned ahead of the Wicklow Way Relay and European Trial. In fact, participation in both those events now hinges on the recovery curve from this. I will not be able to do myself full justice even if I recover but hopefully I can retain enough fitness to put in a reasonable performance in both.
