Hi,
Noted your history of severe blow on knee, knee collapse when going down stairs followed by achy pain for hours, feels like dent pushed in onto tendon, wants to know whether you can wait untill go home as you are on road for 2 months.
Since your history is indicative of a tendon or internal
knee injury, it is most important to know what has happened.
Since X-ray is normal, that indicates only one thing the bones.
For soft tissues and knee
cartilage you need an
MRI.
If there is such an injury it needs to be diagnosed and treated asap.
Hence try to arrange an MRI as soon as possible and get treated under the guidance of an Orthopedic Surgeon.
Till then give rest to the ailing part, apply
splint or so.
Take an anti-inflammatory medicine like
Ibuprofen if it suits you.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, General Surgeon
