Generalized cramps may be caused by the following reasons: 1. There may be epilepsy. Epilepsy is a type of disease that causes limb convulsions due to abnormal brain discharges. The main lesion is in the part of the brain. It may be due to occupational lesions within the brain, or due to trauma or congenital developmental factors, resulting in organic damage to the brain, which in turn causes the above pathological changes. 2, there may be cases of febrile convulsions. There are many patients who have persistent convulsions after a sustained attack of high fever, which is most common in infants and young children.3, there may be a case of corns, that is, cramps caused by tetanus. This is often due to trauma, resulting in infection of the tetanus bacillus inside the wound, which can then lead to persistent muscle spasms throughout the body.
