I have studied your case.
As per your history there can be injury
or ligament of your knee .I will advise to take rest ,ice fomentation ,knee support and anti-inflammatory.
If no improvement in symptoms then you can do MRI
knee to look for pathology.
You may need some blood investigation.Physiotherapy
will help you in reducing pain .
