A spasm is a sustained and involuntary contraction that happens after a muscular effort that implies an overload.
Symptoms: it appears as a decrease in the width of the mobility of surrounding joints, pain (spontaneous and when touching the muscle) and severe decrease of the efficiency of the muscular group that is affected. It can be the preliminary situation of a muscular tear.
-Rest and regulation of the activity that produced the spasm.
-Use of physical, local means: wet heat, deep heat (ultrasound or short waves), professional massage (with use of oils or lubricants), soft mechanical stretching.
-Use of analgesic and anti-inflammatory medication. (It is said that the best way of relaxing muscles is to take painkillers. This is because there is a circular behavior in spasms, which makes a contraction to cause pain and then the pain to cause more contraction. So, by eliminating the pain, one can break that circle and release the muscular fibers).
-Restart physical activity gradually and carefully to avoid a relapse.
