Hi, I've been told stress factures come on gradually but this came on suddenly.
Basically I'm an off-road runner, I'm 62 and avoid hard surfaces and only do about 10-15 miles each week.
However, last week I accidentally did two 5km races on Saturday, on tarmac.
On Monday I did a 21 mile moorland walk/jog, with a 2 mile downhill jog to finish, on tarmac, in my trail shoes. I felt fine but a bit stiff in the hips and knees.
On Tuesday I walked 6 miles to a mountain hut and then jog/walked 1500 vertical feet back down the rocky tracks again in my trail shoes.
On Wednesday I walked to the top of the UK's highest paved road (Great Dun Fell) then jog/walked 2000+ feet descent over 4-5 miles on tarmac back down (very steep in places), again in my trail shoes.
On the way up I had felt a tightness in the lower part of my left shin but just thought it was muscle stiffness. On the way back down everything was aching but I did notice that the tightness in my shin was now a dull ache.
After getting back to my digs I went for a brief shakedown walk and immediately got a lot of pain in my lower left shin. On inspection there was a hot red spot a few inches up from my ankle. The next day a yellow bruise appeared about 4-inches across.
I suspected a stress fracture and have iced it and largely stayed off it since. Each morning it seems better, but if I do any prolonged standing I get a localised stabbing pain in the shin. Its 5 days of immobility now. Clearly a return to running is out of the question for several weeks, however I would like to get out on the bike, but i'm not sure I should until I am pain free standing.
Any advice on this ? how long until I should be able to start walking again?
