A cortisone injection is helpful to decrease inflammation around the nerve roots, but the pain relief usually lasts less than a few months. Before opting to cortisone shots, doctors usually try less invasive treatment methods first like oral medications and physical therapy. Before giving the injection the skin is usually numbed with the help of a local anesthetic. In trigger-point injections one may feel a sharp pain or muscle twitching when the needle hits the knotted muscle. After the corticosteroid injection the injection site may be a little sore and swollen. If corticosteroids are injected directly into tendons or nerves, it can cause severe damage.
It is suggested to discuss your queries and concerns with your attending doctor before taking these injections. Hope it helped.
Best wishes and regards!
Thank you ASharmaMD. I have tried oral Steroids and physical therapy and neither have helped long term. I have developed Muscle knot (trigger points) in the past 6 months that cause me to be pretty much immobile. I cant lay, side or stand comfortably. I feel like I'm getting no relief and the only treatment the doctors suggest are narcotics which make me feel and sometime nausea.
Any suggestions. I have been told that surgery is out of the question due to scar and vascular area at site.
