i have similar back issues. my last major spasm occured just before a long haul flight with my 8 mth. old daughter.after recieving a full body massage , my spasms actually got worse.Don,t get me wrong thou, I do advocate massage! i then went to the doctor who prescibed a combo of pain meds, muscle relaxants and anti inflammatories. It all kicked in immediately and made my journey very comfortable instead of a horror show. I find my spasms are brought on when i am under constant stress and don,t have time to relax. I am a "doer" personality , so now I try to recognize when I am holding a lot of tension and try to relax and stretch out(yoga is very helpful). My advice would also be to cut back on lifting heavy things ie;baby! strollers , groceries.Also , limit how much vaccuming and mopping you do...very stressful on the back muscles as it is so one sided.Once a muscle is inflammed it needs to be rested until the swelling has reduced.Epson salt baths can also be very helpul as the magnesium salts will relak the muscle. Aromathery oils, such as rosemary and thyme in an oil blend can also relax muscles.All the best!
