On April 6th, I went into the ER for back pain. After I had an x-ray that turned out to be fine, it was determined that it was just a muscle injury. I was then given an injection into my right buttock of Norflex. Soon after I was given the injection, I became sedated, and when I was discharged and tried to walk, I noticed that I had a lot of tingling and numbness from the waist down. I was given a prescription for 100 mg of Norflex. After 2-3 days on the medication, I returned ER with a drug allergy. The allergy is now gone. Now, 5 weeks later, I am still continuing to have numbness and tingling in my right leg and I have sharp pain in my buttock and down the center of the back of my leg. When I followed up with my regular doctor, he suggested that perhaps the initial injection may have swelled up and hit my sciatic nerve. (He said that if the injection had been directly to my nerve it would have been quite painful, and I don't recall having pain during the procedure, just gradual numbness.) He started me on a course of prednisone for the possible swelling, and referred me to a neurologist. The prednisone didn't seem to help. The neurologist gave me an EMG test to check for nerve damage, but to my suprise, the results came back to be normal. I returned last week to my regular doctor, who suggested that since the EMG was normal, there has been no permanent nerve damage, and prescribed me Gabapentin, but due to side effects, I've had to stop taking it.I called my neurologist back, he isn't available until July, but I talked to the nurse who said that she'll speak to the doctor to see if he has any suggestions. I'm also trying to get in to seeing a pain specialist. My question is that why would the EMG come back to be normal if I am having tingling and numbness? Is this just temporary? I am concerned that I may have serious nerve damage if the injection I had hit my sciatic nerve directly.
Would an injection of lidocaine and methylprednisone help my symptoms?
