Tip 5: Punctuation can enhance your search as well. Use quotes ("search term") to only include pages with the same words in the same order. But only use this if you are looking for an exact word or phrase, otherwise you may exclude helpful results. Add an asterisk (search term*) as a placeholder for any unknown or wildcard terms. For example, C*l Tunnel would give you results for Cubital Tunnel and Carpal Tunnel. Place a question mark (search term?) for single-character wildcard matching. For example, pa?ent would give you results for parent, patent, etc. You may also use the plus sign (search + word) between words for words you must have in the results.
Cervical Epidural Steroid Injections involve injecting a steroid into the epidural space of the cervical spinal canal where irritated nerve roots are located. The injected medications include both a long-lasting steroid and a local anesthetic (Lidocaine, Bupivacaine).
The steroid reduces inflammation and irritation, while the anesthetic interrupts the pain-spasm cycle and nociceptor transmission (Boswell 2007). The medicines spread to the most painful levels of the spine, reducing inflammation and irritation. The entire procedure usually takes less than 15 minutes.
