Many thanks for your reply. I was already thinking of asking for another MRI to see what’s going on. Possibly an MRI of my hip too. Whilst my issue is very painful. It doesn’t sound quite as severe as yours was, though the suddenness of the onset of pain after several weeks being pain-free could easily be caused by the same thing. I guess the only way to check is by repeating the MRI. I’m seeing my GP on Wednesday this week and I will mention your case to him. Thanks again I’m very grateful.
