I started playing badminton regularly for past 5 months. A week ago I was playing a club tournament and playing intensely. Halfway through match I picked up the shuttlecock from the floor and immediately had an acute pain in my lower back (central area) but I carried on playing to finish the match. During the whole week the pain was intense when I sit in my office chair and shifted towards my left side of my lower back. After few days of rest and pain started to vanish. The next Sunday I went to court and started doing some drills. Just after few mins I landed on my left leg and picked up very intense pain and left home immediately. Checked with near by doctor and he said it might be muscle tear and gave some injection and tablets for few days. Has anyone been in similar injury before? How long does it take to be back in full fitness and play normally?
