Dear Sir, my wife at 68 & of 36kg,is suffering of back pain due to bulging at L4/L5 & protusion at L5/S1.Her such issue is repetitive-2003.2008.2011 & July 2014. after viewing MRI Neurologist prescribed-Shelcal-M twice/day & Cholecalciferol once/week.he also prescribed Calcitonin Nasal spray in alternate nostril. She is advised rest & some excercise. everytime orthopedic surgeon gave pain killer & asked for rest & excercise. She does have Varicose,on Left Leg,since last 30 years & Vasular surgeon,opined to consult Neurosurgoen,as her pain is predominantly on Left side only. Whether this treatment for three months will eliminate this issue? please also advise any other precaution in future.Are you anticipatiing surgery?Do you feel some degeneration of bones in Spine?If you agree,I may submit the comments of Radiologist on MRI. Thanks a lot. anil
