Hi, thanks for writing to HCM.

As your xrays are negative for a fracture and you still experience severe pain in the knee, I suspect intraarticular soft tissue injuries either the meniscus or the ligaments (ACL,PCL or Collaterals).

An MRI scan is needed to diagnose any soft tissue injury inside the knee joint.

I assume that your heel numbness could be due to a tightly applied brace which might be pressing over the superficial nerves. Just loosen the brace lightly to resolve the numbness.

Hope this information is helpful. Good day

Thanks for your query.

I would advise you to wait for 2-3 days more before going for any further rest.
Take your doctors medicines as prescribed. He might have given you painkiller medicines to decrease the pain & swelling. Take rest, dont put pressure on your leg that will delay the healing process. Avoid walking as far as possible for a day or two,this will give rest to the joints.Apply locally ice to your knee.

If pain doesnot improve within 2 -3 days than you can consult your doctor again.
Take care.
