leg cramps

my lower left leg hurts. early this morning (around 1:30 to 2:00am), i woke up because both my lower legs were cramped. i didn't know why they became cramped, but it was not something i look forward to happening again. so, after a few minutes of leg stretching, the muscles finally relaxed, but the pain on my lower left leg stayed there and until now it's still painful. i can (barely) walk straight because the muscles get pulled and i have to walk slowly. i slept in the quarters and when i woke up, my lower right leg became cramped again, but the muscles relaxed right after a few seconds. it feels okay now but my left leg really is hurting. the muscles are still somewhat tight. huhuhu...
