I am having severe knee pain for the past six months after 1year of my pregnancy.I couldn't do my regular activities and couldn't walk, sit on floor or climbing stairs.intially my
vitamin d was slow.now it's on good level.All the test like Ra factor, aso latex,
CRP,
uric acid, RBS,Hla, anti -ccp is normal and negative.My MRI scan shows ACL sprain and joint effusion.I couldn't walk or sit freely till now.Is this an arthritis?Do I need any physiotherapy?.I have attached my scan report here.
