Hello, Few years back i was having lower back pain on my right side. I think it came due to improper lifting or pushing a heavy object. I felt pain after walking long distances and for few minutes in bed. Pain was there for few years. I started physiotherapy for it. It was there after i did physio exercises. Then after i left physio in few months it went away. Now it has completely gone. I can walk long distances with no pain and i cant feel any pain in lower back. Was it a muscle spasm or something else? I never went to any doctor as the pain was always mild. Can i continue gymming exercises?? I am not doing lower back exercises from some time. Should i do those exercises regularly. Please suggest..
