I had a cortisone injection into my hip for diagnosis of buttock and leg pain, three days ago.Every day have had at least 2 episodes of sharp, burning pain- muscle cramping ? -deep in the hip. I ice it, and subsides. I have resumed gentle walking , one hour a day , with frequent stops. Worst episode came after2 hours sitting.bizarrely, getting sharp pain around left ankle when I weight bear- sporadic.totally new! Too far from the right hip to be connected, surely?
