I ain't likin' it. BTW What is a back spasm? Muscle pain?
From a google search...see the bold below...
A back spasm is the involuntary contraction or tensing of the muscles in the lower back. The condition ranges from infrequent spasms with mild discomfort to chronic spasms with severe pain that makes it difficult to move. Back spasms can typically be treated effectively without surgery.
The primary factors in recovery time are the severity of the injury and the treatment approach. A very mild muscle pull can heal in just a few days when rested, but most muscle strains may take four to six weeks to heal, and a very severe muscle pull could take up to ten weeks.
