I get trigger point injections with lidocaine and steroid all over my back, and I get paravertebral and intercostal nerve block injections with lidocaine and steroid for the front of my torso--the back and front injections help tremendously!!
A regular MD, who works for my MS specialist, gave me the trigger point injections for my back, and an anesthesiologist, who specializes in pain management, gave me the paravertebral / intercostal nerve block injections for the front of my torso (which were actually given on the sides of my torso).
Because there is a small risk of pneumothorax (collapsed lung), fluoroscopy might be used to help guide the needle to just under/behind the rib where the intercostal nerve is located (this is called "walking off the needle") for the paravertebral / intercostal nerve block injections. I can actually feel the pressure when the needle is "walked off" my ribs, but this does not cause pain --I urge you to remain still when this is being done!
All these injections last from six to eight weeks for me; your mileage may vary. One drawback about these injections is there's a limit on how much steroid can be given per injection and per year. The lidocaine is short-acting so that the needle can enter without pain; the steroid is long-acting and is what actually helps stop the MS Hug pain.
I still need to add this information to my first post. These injections are saving me from jumping off a bridge. I hope the injections help you, lovebug. Please let us know how you make out with them and what you learn! Thx!
The intercostal nerve, which is the small yellow dot, is easier to see in the bottom depiction.
Picture in your mind the doctor feeling, with his/her finger, the bottom edge of your rib, then pushing in the needle at that location, then by using tiny increments, "walking off" the point of the needle until it reaches just under the curve of the rib bone but not too close to nor into the nerve itself. Use of fluoroscopy can also help guide the needle. Clinical experience counts.
Hope this helps.
