Cause #9: Toxins
A toxin is a harmful substance capable of causing disease when it comes in contact or absorbed by body tissues. Toxins can range from mild toxicity to deadly. In some individuals, high levels of toxins such as mercury or lead can result in calf or leg cramps.
Mercury poisoning can also cause skin rashes, numbness in the extremities, muscle weakness, trouble speaking, visual issues, difficulty hearing, and memory problems. Lead poisoning can cause headaches, irritability, abdominal pain, memory issues, paresthesia in extremities, anemia, and seizures, among others.
