I am sorry to hear that you are having such bad leg cramps, and would like to suggest that you see a doctor
. While many things could be the cause of these cramps, most of them are somewhat obvious and almost all are self-limited. The fact that you don't mention these in your question makes me think that seeing a doctor sooner rather than later would be wise. Obvious causes of leg cramps would include a new exercise program that has you working much harder than you usually do. Also, an inadequate diet, one that is poor in essential vitamins, minerals, or nutrients would possibly contribute to this complaint. As a 38 year-old, however, even this would have to be quite severe for your problem to persist for some time and to be "debilitating." In the absence of these obvious factors (or some other part of your medical history), there may be some other cause. Lack of adequate blood flow, fuel, or oxygen to the muscles is usually at the heart of muscle cramps, with the other possibility of poor fuel utilization. If you are having continued cramps, please speak with your doctor to see if there is a cause that can or should be corrected or treated.
