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.
Epidural steroid injections are generally very safe, but there are some rare potential complications. One of the most common risks is for the needle to go too deep and cause a hole in the dura, the tissue that surrounds the spinal cord and nerve roots. When this occurs spinal fluid can leak out through the hole and cause a headache . This headache can be treated with bedrest, or with a blood patch. A blood patch involves drawing some blood from the vein and the injecting it over the hole in the dura. The blood forms a seal over the hole and prevents any further fluid from leaking out.
