For about 4 days I have been having lower back pain and also pain on my lower left side. Also dizzyness and headaches which I never get.  I had a hard time walking and getting up last night not as bad today I have been taking ibprofen to day some comfort not much.
Dear patient This may be Muscle spasm or back sprain. Have you injured your back recently or lifted heavy weight? Both may be reason for sprain.  I would advise X-ray of lumbosacral spine anteroposterior and lateral views to rule out bony abnormalities. If its normal start tab diclofenac plus thiocolchicoside combination twice a day and tab attract p one at bedtime for 7 days. Apply nice gel locally at site of pain thrice a day.  If X-ray report is abnormal need to consult expert orthopedic surgeon.
