been a runner for more than 40 years and last night for the first time ever, i woke up in the middle of the night with a major cramp in my shin - tibialis anterior - totally locked up. could not press my foot down with my hands.
finally let go with some massage.
today it's very sore.. sorta like instant shin splints. doesn't 'hurt' but i can feel it when i walk.
i've had night-time calf cramps galore over the years... the occasional hamstring or quad twinge... but never in the tibialis
ever experienced this?
any idea what might have caused it?
