Back spasms can be the result of injuries to the muscles, tendons, and ligaments in the back or it can be related to more serious medical conditions. Heavy lifting is a common cause of back spasms. Any activity that puts excessive strain on the muscles and ligaments in the lower back can cause an injury.
Muscle spasms, cramps or twitches are involuntary and sometimes painful movements or contractions of the muscles within the body. They can occur if a muscle is overused, such as during exercise, and if you are dehydrated. Low levels of potassium and calcium can also cause muscle spasms. Muscle spasms can also result from alcoholism, hypothyroidism, kidney failure and certain drugs and medications, including caffeine. Muscle spasms and cramps can usually be relieved by stretching your muscle and increasing your fluid intake.
