I had it years ago - forget which leg - but I believe I had it for almost 9 months or so!
I remember being in work and walking on my toes due to the pain.
The only thing I did was first used the heating pad on my buttocks when I could....but then was told ice is better so I used ice packs even when in work. I was lucky with my co-workers, no one thought it was strange I was walking around with an ice pack tucked in my pants.
And, of course, there is always PT but I didn't even do that. And with the passage of time (a long time) it went away. Good luck to you.
