It would be a muscle spasm which happens due to sudden jerky movements. However if you observe swelling over the lower back it would be advisable to get an x-ray done. Otherwise just rest and application of warm oil along with hot fomentation (hot water bag) for 3 to 5 days will relieve the spasm. Avoid any strainous activities during this period till the pain subsides.

Get an xray limbosacral spine done in standing position.Chancer are there for mild dislocation of lumber vertebra and suprresion of corresponding nerve.Quick action is needed and treatment include panchkarma treatment where massage with medicated oils and steam is given as well as other procedure like kati vasti is done (panchkarma proceedure). Along with this you should consult ayurvedic doctor to start the medicine for the same.

There may be a chance if some sparin or some thing over there....as ur age is 27 there may be not a big issue of something related to bone....i may be a mascular pain...but i will advise to avoid any excerise even without weight for some around 15 to 20 days..and have these medicines u will feel relief.... I would like to advise to not to take any pain killer because u knw pain killer gives u temporary relief from pain and its block the pain signal from brain so person feels relax and do the movements of that part and in muscular pain or sprain the main treatment is that to give rest to that part otherwise damage will increase over there...so its nly damage that part and problem increases....

Obviously don't do exercises for few days, get a x-ray or MRI spine to know the actual problem. Local application of pain relieving gel or hot oil massage will be good but don't think to do anything immediately.

Hi . it might be due to spasm of muscle . but I'll recommend you to get done x ray of back . in some cases we find little shifting of vertebrae . in such cases you need to stop exercise.

This may be due to muscle spasms. Avoid exercise till pain subsides. Take rest.
