Can anyone shed some light on what might be causing this and what I should do please?
I have been upping my mileage in preparation for the Fellsman and done a lot of long runs in mud and snow. The day after a very difficult 18m run in snow last week I felt pain in my inside right leg about 3 inches above the ankle. I have been favouring that leg a bit on descents due to a flair up of an old knee injury on the other leg. I rested for a day and then had a short run which was uncomfortable but not too bad. Had two short runs since and thought it was a bit better yesterday but when I went for a 3m walk it got progressively worse until I had to limp home. I've massaged the area and it feels very tender if I press it and also 'creaky' if I flex my foot while pressing. If I go on tip toes I get a sharp stabbing pain. I'm really fed up. I have had physio treatment for my knee and a badly sprained ankle last year and have started doing the exercises again but its slow progress and I'm really bad at remembering to do them (I am going to try really hard from now on). The exercises are things like squats, calf raises, glute strengthening and core work.
I've been trying to work out what muscles and tendons are involved in the most recent problem from anatomical drawings but I'm really confused. I just want to keep running and I feel demoralised. Can anyone offer advice? I know I can go back and see my physio but I am hoping there is something I can do to help in the short term.
