ANKLE INSTABILITY

I sprained my ankle 7 weeks ago after stepping in a pot hole in the dark.
What I thought was a simple inversion injury has turned into a very painful situation.
I was diagnosed with an atfl spain, told I had no instability though found out 2 weeks later I have significant instability, placed in an aircast, and sent home on crutches.
I returned to work as a respiratory therapist(a job that demands my feet) 3 days after the incident, limping and in an ankle brace.
My ankle starts to throb after 20 minutes of continuous standing and 7 weeks later is still doing the same.
The swelling, tenderness and ecchymosis is around the atfl and mallous.
I pay for standing every night.
The pain is incredible, night pain is even worse.
I am no longer able to work or stand for more then 30 minutes at a time.
Swelling is still persistant.
Ankle is very wobbly and at times the pain is so bad, I can’t stand at all.
Swelling is also located bilaterally around heel.
I am able to stand on my toes but shake.
Pain is sometimes bilateral in nature around both medial and lateral sides of the heel.
X-rays are normal.
This ankle has been broken twice through the epiphysial plate and sprained numerous times.
Never had a sprain that had pain that persisted this long.KIM
