You might have twisted your knee again while playing badminton. Aching dull pain when you try to straighten or tighten your knee could mean the ligament has been pulled too hard.

Based on your CT scan, it looks like you have some fractures in your ribs, which could be causing the pain in your back when walking. The hemothorax next to your rib fractures is a collection of blood outside your lungs. This might be making it a bit tough for you to move around comfortably. It's great that you are resting, which is really important for healing those fractures. Make sure to keep monitoring your pain levels and follow up with your doctor for any further guidance.
