After back surgery, you will have to stay for a minimum of 3 days in the hospital. However, it completely depends on your condition and treatment received. Even after getting discharged from the hospital, you should take as much as rest as possible to recover faster. Your doctor might check you and advice physical therapy as soon as 24 hours. But to recover completely, it will take you 3 to 4 months. Specialist Hospital conducts Spine surgery in Bangalore, which is followed by physiotherapy and rehabilitation.
