Over the last 7 weeks I have had 3 steroid/cortisone injections to cure my bursitis. X-ray results have proved that there is nothing wrong. I am in constant pain. Co-codomal tablets spaced me out. Last injection I had was last Friday 18th December. I have been told I have to wait for a further fortnight. It is really getting me down. I cannot walk much without terrible pain shooting down my left hip and buttock and it catches my breath. What do I do. Ask for MRIscan ? Go back to dr.
