What can cause cramps in my lower abdomen, lower back pain, and numbness in the legs at the same time?

Several issues. See a back surgeon and get examined and have this corrected. The sooner you go the better the chances for full recovery. If you ignore nerve damage too long it may be too late for complete reversal. Best wishes.
