Asking for a clarification is not synonymous with telling you you're intruding. Perhaps that's merely a regional difference.
Muscle spams have several "causes" and I'm only initially referencing the one's that are established by peer-reviewed journals and what many call "modern science". Either the cells of the muscles are not receiving the proper fuel (potassium, magnesium, glucose), they are being over worked, or there's an impediment/dysfunction in the nervous system.
Muscles basically spasm to prevent you from doing further damage to them. They seize up like a splint or cast in order to protect by immobilizing. If you are having them (spasms) regularly then you can try moving from simple to complex. The first level is amending your diet which means a focus on nutrient-rich foods and an avoidance of that which leaches minerals from the body (read: coffee). Almonds, cashews, soybeans, and deep green leafy vegetables are magnesium-rich foods.
The second level is amending your practice. If that practice is daily and varied then it may be its intensity, either by itself or in conjunction with other "things" you do. If it is not varied then perhaps a shift in one's practice so that the body's needs are met day in and day out rather than providing it only one thing over and over again.
One might also consider looking at immune system function to make sure everything that is supposed to be operational is operating. There are a variety of things that effect the nervous system (including environmental toxins and dis-ease) which could in theory account for ongoing muscle spams.
