Hello madam,
U need a personal thorough evaluation. Meet an orthopaedic surgeon. Stage 2-3 AVN will progress to more worse so finally would need total hip replacement. You can delay by using bisphosphonate tablets and core decompression surgery which is a minor surgery.
Next Steps
start over tablet Alendronate 70 mg once a week for 8 weeks, to be taken early morning empty stomach. We'll see how you progress over this. Kindly try meeting nearby Ortho surgeon ASAP.
Health Tips
avoid squatting, using indian toilet, sitting cross legged. Do some hip and knee ROM exercises. All the best we're with u always
