Detailed Answer:
Hello,

I have studied your case.
I would like to give differential diagnosis for your symptoms and history.
There is possibility of Deep vein thrombosis leading to leg hardness and lump.

Ultrasonography/colour Doppler leg will help to rule pathology leading to pain like deep vein thrombosis.
Another possibility of nerve compression leading to pain and numbness in leg and back side of knee.

I will advise you MRI spine to see for any nerve compression.
If required you may need to do blood investigation for prognosis and recovery.
I will advise to check your vit B12 and vit D3 level.
