Hi,I have been having lower back pain for about 3 weeks. I have been having mild right hip and right knee pain and stiffness for the same amount of time. When I push on my stomach around, and especially just below my belly button, it feels like a small ball and hurts my back a lot
Firstly get an X-ray done for your back spine and do visit doctor if you are heavy reduce weight since you didn't mentioned your age It's difficult to diagnose whether it's a degeneration case or any other injury. Till then, you can do hot fomentation for your back and ice therapy for knee for 10-15 mins .do not lift heavy weights and no forward bending. Use good knee while climbing stairs and bad knee while getting down from stairs
