Hi, Thanks for using the HCM.
While standing up you might have hurt your ligaments in your right joint. There are certain manual tests/investigations to identify which ligament injured. Since the injury
is old you need some basic investigation to see exact type of injury. So better consult your Orthopedic doctor, get correct diagnosis and then the treatment ll be based on it. It may be simple exercises, physiotherapy
to mild surgery if required.
Hope I have answered your query. If you have any further questions I will be happy to help. Thanks get well soon....
